How long does it take to recover from Metformin Fatigue

Posted by leigha67 @leigha67, Feb 17, 2025

Hi, I'm Leigha. My new endo prescribed Metformin for prediabetes. ) I've been on it a month, and went to ER this weekend with serious back pain and fatigue. I'm just sleeping all the time, which isn't like me at all. The ER doc couldn't find anything wrong and told me to stop taking the metformin. Has anyone else experienced these symptoms? How long did it take to recover from the fatigue? I'm torn between whether to stay on 500 mg dose once a day or drop it altogether. I usually take 1000mg (500 x 2 per day). I will be calling my doctor for an appointment today. Just wondered what others have done?

I had been taking Metformin for over 10 years. It took me years to figure out the connection between taking Metformin and my constant fatigue. I was always tired. I would get home from work and lay down to relax and I would be asleep in a minute and then easily sleep for 3 hours. I suffered from a total lack of motivation. When I realized that my symptoms started around the time I began taking Metformin, I stopped taking it. This was about 2 months ago. Since then, I don't sleep 12 hours a day on weekends and my motivation has improved greatly. I am now taking the supplement Berberine, and the highest my blood sugar has been is 164. I believe Metformin does more harm than good. A friend of mine who has diabetes asked his doctor if Diabetes can be reversed. Her answer was "Yes, but I am not supposed to tell patients that it can be reversed". Are our doctors getting commissions from pharmaceutical companies when they prescribe drugs to their patients?

@cewmyers57 I don't want to sound jaded, but I guess I am due to the fact that I see all the drug reps with their leather briefcases full of "goodies" waltzing in and out of the doctors office while their waiting rooms are full of their patients waiting to be seen. Aside from Big Pharma influence on how and with what we are being treated, I have a problem with setting a universal "one-size-fits-all" number that determines which side of diabetes you're on. No 2 people are alike and we all show up with our own individual bodies with all their unique facets, so how can you draw such a line in the sand. Should there be "guidelines", of course, but mandating that every one on earth has to be at a certain number set in stone is unfair and unrealistic . . . but it does sell medication.

Hello and thanks. I had to go off it. It was making me sick. I take Berberine instead now. Thank you for asking!

I have other health issues (GBS). Still, I've been renovating my place and seem to hit a "wall".
It feels as if the very cells in my body have run out of energy. My breathing gets ragged. I have to stop what I'm doing...NOW. I also seem to get MADDENING itching, at a different spot, each time.
I had a pancreatic attack, 18 years ago and biked my way out of the diabetes I was diagnosed with. But even then, I noticed that "wall". It prevented me from biking as I wished. I could do half, basically, of my normal rides. I'd get so tired and had to "limp" home.
I unilaterally stopped the pills and the problem went away, soon after. So fun watching my nurse and doctor argue about whether I'd just "cured" myself.
"Nurse. You know darned well there's no cure for t2 diabetes."
"Well doctor. They had diabetes and now they're normal. What would yo call that?"
"I don't care what you call it, there is no cure for diabetes!" Etc.
I'm now in my late 60s and biking my way out isn't an option. However, with a grain mill, organic gardening and of course, THCv, my A1C has been a steady 6.2 for 6 months. Down from 11.0, a year ago!
6.2 is not great. Not as good as the 5.6 I achieved on CBG isolate (800mg/day). But I got a medical grow license from Health Canada and just harvested my first THCv crop. This has tripled the dose of that very expensive cannabinoid. DEFINITELY engaged my ECS (endocannabinoid system), and my symptoms have all but disappeared.
My question now is: at what point do I try to "work without a net" and stop the pills?
This fatigue hampers everything I try to do. And while it may well be linked to the Guillain Barre, I can't help thinking the metformin is the cause.
My doctor is in her first months, as my former doctor ran away to England to get married.
She has no experience, even if she's very smart.
Anyway. I'm tempted to pull the trigger. Almost as much as I'm worried about my glucose spiking.
Maybe this summer...

RESULTS

Compared with placebo, THCV significantly decreased fasting plasma glucose (estimated treatment difference [ETD] = −1.2 mmol/L; P < 0.05) and improved pancreatic β-cell function (HOMA2 β-cell function [ETD = −44.51 points; P < 0.01]), adiponectin (ETD = −5.9 × 106 pg/mL; P < 0.01), and apolipoprotein A (ETD = −6.02 μmol/L; P < 0.05), although plasma HDL was unaffected. Compared with baseline (but not placebo), CBD decreased resistin (−898 pg/ml; P < 0.05) and increased glucose-dependent insulinotropic peptide (21.9 pg/ml; P < 0.05). None of the combination treatments had a significant impact on end points. CBD and THCV were well tolerated.
CONCLUSIONS

THCV could represent a new therapeutic agent in glycemic control in subjects with type 2 diabetes.
