I suplement with Arginine 1000, Jarrow. I really do not have a handle on what is/is not helping. I am feeling better, less brain fog and fatigue is less but muscles still very sore, stiff, twitching. I have actually backed off my suplements and taking minimum for the last 4 wks (Metanx, CoQ10, D3 5000 daily; Arginine, diribose multiple times per week). My body aches all over but not having brain fog making a huge difference. Can function more, do more tasks but still dont feel well.
