Only been sleeping 3 hours a day and regular melatonins aren’t working

Have you spoken with your PCP or spoken with a Sleep Center to do a sleep study?

@malebreastcancer47
Unfortunately I have not

Please excuse the grammar issues I’m dyslexic and very tired 😭

@wii No worries.

I do not know what your root issue is and will not suggest taking more meds if other respondents suggest.

I have used Melatonin, it cannot be used daily and over time, after a few weeks, its stops being affective. No more than 10 mg unless a doctor prescribes it. I have used magnesium supplements and now drink chamomile tea before bed.

If you can, suggest requesting a consultation with Mayo.

I'm bipolar and have the same issue. doc said try L-theanine and magnesium it worked for a couple of days but that was all. Sometimes if I wake at 3 am or do an all nighter I find I am sleepy when its the time I really should be getting up to go do stuff.

I completely understand lack of sleep. 3-5 hrs a night is a lot for me. Went to a sleep hospital yrs ago, was told I wake out of my REM 25 times a night! No wonder I wake exhausted! Some things have helped me. I bought a new mattress. Not just any mattress, a vegan organic all natural one from Avocado Mattress Company. No animal products, no springs, no box springs, no chemicals. I added the pillow top, mattress protector, and two latex pillows with carbon inserts which cleans the air with every breath you take, $125 a pillow, and got the protectors for them. I'm a side sleeper. The whole unsombul cost a fortune but the very first night in it, I work with a crease on my face and drool on my pillow. It was the first deep sleep I had in years!!! Every night I am grateful to have it to sleep in. No
formaldehyde! Yeah! 😃

Most people take too high a dose of melatonin.

What studies show about melatonin dosing for insomnia

Across clinical trials and sleep‑medicine guidelines:

0.3–1 mg often mimics the body’s natural melatonin peak

1–3 mg is the most commonly studied range for insomnia

Researchers have repeatedly found that lower doses tend to work better for sleep‑onset insomnia because they avoid “melatonin hangover” the next morning.

Timing matters more than dose

For insomnia, studies generally show melatonin works best when taken:

1–2 hours before desired bedtime

At the same time every night

Taking it right at bedtime is less effective because melatonin is a signal, not a sedative.

Why melatonin sometimes doesn’t help

Even at the “right” dose, melatonin is most effective for:

Delayed sleep phase (night owls who can’t fall asleep early)

Circadian rhythm issues

Jet lag

It’s less effective for:

Middle‑of‑the‑night awakenings

Poor sleep caused by stress, pain, apnea, or restless legs

General insomnia without a circadian component

Why low doses work better than high ones

The key idea is this: melatonin is a hormone, not a sedative, and your brain is extremely sensitive to it. Once you understand how the biology works, the “low‑dose works better” pattern makes perfect sense.

The core reason low doses work better

Low doses (0.3–1 mg) mimic the brain’s natural melatonin signal.

High doses (3–10+ mg) overwhelm it.

Melatonin’s job isn’t to “knock you out.”

Its job is to tell your circadian clock that night has begun.

When the dose is too high, the signal becomes noisy, prolonged, and mistimed, which can actually delay sleep or cause next‑day grogginess.

1. Low doses match the brain’s natural melatonin peak

Your pineal gland normally produces about 0.3 mg of melatonin at night.

When you take a low dose:

It gently raises melatonin to a physiologic level

The brain recognizes it as a normal “nighttime” cue

The circadian clock shifts earlier, helping you fall asleep

High doses, by contrast, create supraphysiologic levels — sometimes 10–100× higher than natural.

That’s like shouting a whisper.

2. High doses saturate receptors and stop being useful

Melatonin receptors (MT1 and MT2) saturate quickly.

Once they’re full:

More melatonin doesn’t create a stronger effect

It just lingers in the bloodstream

The “signal” becomes smeared across the night instead of being precisely timed

This is why people often feel:

Morning grogginess

Brain fog

Vivid dreams

A “melatonin hangover.”

3. High doses last too long

Melatonin has a short half‑life (30–50 minutes), but at high doses:

Blood levels stay elevated for 4–8 hours

The brain still thinks it’s “night” when you wake up

This worsens sleep inertia — something you’ve struggled with before

Low doses clear more quickly, giving you the signal without the hangover.

4. Melatonin is a timing drug, not a sleepiness drug

This is the most misunderstood part.

Melatonin doesn’t sedate you.

It shifts your circadian rhythm.

Low doses shift the clock cleanly.

High doses can actually push the clock in the wrong direction, especially if taken too late.

This is why some people say melatonin “does nothing” or “makes sleep worse” — the dose and timing are fighting their biology.

5. Clinical trials consistently show a U‑shaped curve

Across studies:

Very low doses improve sleep onset

Moderate doses help some people

High doses add side effects without improving sleep

More melatonin ≠ more sleep.

It’s the opposite: more melatonin = more noise.

6. High doses can disrupt your natural melatonin rhythm

Your brain expects melatonin to rise at dusk and fall at dawn.

High doses can:

Flatten the natural rhythm

Reduce the brain’s own melatonin production

Make sleep timing less stable

Increase morning sleepiness

This is especially relevant for people with sleep inertia, because melatonin lingering into the morning amplifies that “stuck in molasses” feeling.

The takeaway

Low doses work better because they cooperate with your circadian biology.

High doses fight it.

Great information. Where did you learn all that? Thank you.

I stopped taking melatonin because it did nothing for me, but I was taking 10 mg. After years of sleeping problems which started about 20 years ago with menopause, I am seeing a sleep doctor the first week of June.

The only thing that ever helped me was CBD tincture. But after a couple of years, that stopped being effective too. My greatest problem is waking up at 2/3/4 in the morning. I usually don’t have a problem falling asleep.

I love green tea, but stopped in many years ago because I am so caffeine sensitive. Yesterday I made a small pot of quality green tea first thing in the morning. I wonder if that is why I got such little sleep last night.

I decided I am not taking sleep meds any more. They were of little effect ( tried 5 different ones) and the side effects at my age are not helpful. I have no problem falling asleep just don’t stay asleep. My pattern is to wake up every 90 min. I was getting up using the bathroom, getting a drink and back to bed. Usually by 4 I don’t go back to sleep so get up. My doctor said I should not get up and go to the bathroom (unless I really need to) as it increases the level of awakeness. I am now trying Venus nerve stimulation ( recommended by a chiropractor) and the initial results seem promising. I first noticed that despite my sleeping pattern not changing I seem to get better sleep quality and didn’t feel as tired. Last night I slept an hour, woke up, did something that relaxes me ( for me prayer) then fell back asleep. I slept 4 1/2 hours which is unusual. I’ll post more as time goes on. I’m also keeping a sleep log for my doc to review. I do have sleep apnea but don’t handle the mask well so gave up on that. It was not severe so my doc approved it. If you haven’t been tested for apnea I would suggest doing it. Many people can handle the mask, nasal pillow or half mask and say it makes a difference. Hugs to you all may you find rest.

@wii
Me too.
