It is like having the flu for 12 hours, fatigue, & recycle.Can this be overdos. It is a cycle of being freezing cold and "sick" feeling, then approx. 6-12 hrs later I'm weak. I get overheated and cold sweats if I move around. Also my depression that I'm treated for gets real bad. This goes on for a few days, then I'm ok and then it starts again. I was wondering if I'm accidently being overdosed.
