Of course, you can do the mito supplements. They are more expensive than some others. But a month on the drugs? That is not long.

Acetyl Carnitine would be the primary one to try... 500mg a day in 2 divided doses, increase to 2000mg a day if necessary slowly.

I'd rather you do the obvious stuff first. Then move on to the mito supports. This way you might improve...and not need more.

The vaccines are problematic, over the long haul. HepB has a checkered past with triggering autoimmune disorders. But do the obvious things first. The muscle twitches, are really common when blood sugar is LOW. Liver damage would prevent gluconeogenesis during lows... low cortisol the same. It can get really complicated. So start slowly ..and I know you are frustrated, etc, and that is hard to reign in. But starting slow is best.

Low D will also impact muscle and nerve pain, so get that tested. Most Americans are quite low in Vit D. I'd cut back on working out to a more modest type that is less stressful. Let your body guide you in this. It is easy to do "what you think you should do based on the media, etc" but it might help to be more modest in working out. You can still do some, just not so much.
