If you have not tried Low Dose Naltrexone (LDN), give a tiny dose a try. I stated at 1.5 mg and it stopped some of the constant chronic pain from Long COVID. I slowly worked up to 3.5 mg and most of my pain is gone. It has also improved my shortness of breath and gives me a little more energy.

I had few side effects but did experience extreme sleepiness for the first two weeks but it was only for an hour or so right after taking it. After that initial period, now it gives me insomnia if I take it after 3 pm. It does give you vivid trippy dreams...not scary but kind of wild, unrealistic circumstances...like sitting on top of a very high dresser watching the sky.

It works by blocking your endorphin receptor for a few hours and then your body makes extra endorphins which for me equates to a little burst of energy about 2-3 hours after I take it. And you will know when you find the right dose for your body...I worked up to 4.5 mg but felt better at 3.5 mg so dropped back down.
