So, awhile ago I forgot to pick up my Valcyclovir and then I ran out of money so I went quite a few weeks without it. My husband and I experience involuntary muscle twitching. A few weeks after not taking the Valcyclovir the twitching was worse then ever. Just for the hell of it recently I tried going off it again. Once again twitching all day instead of only at night when I lay down. The only other correlation with the twitching is when I get the flu or very little sleep it is worse. I am kicking myself right now. Why didn't I think of trying going off of it before? Anyway, I am now very interested in any connection between herpes viruses and CFS or Fibromyalgia. Now on to convince my doctor. I have little faith that I will be able to do that. I think I may be on to something though. My dad said he would try to get me some low dose naltraxone from Mexico. I am not having any luck convincing any doctor to prescribe me any.
