Hello, I am going to a new Fibro and CFS center in my area. They have put me on allsorts of different treaments plans. I have activated EBV and they are putting me on a very high dose of Valtrex along with many nutriceticals one being TF 4000. I constantly feel like I have the flu (fever, chills, achiness) so if I start to hex how will I know the difference? I am suppose to take 3 tablets daily but after reading the posts I think I will start with 1. Also, what does pulsing mean? I have so many things to take I think I will add one at a time to feel the effects. I am so nervous to take it though but if it will make me better I will give it a shot.
