I started taking Acyclovir 800mg a week ago and am feeling very symptomatic, almost like a healing crisis. I don't suppose that is what is happening but I feel even more tired and achey and the brain fog. I seem to have averted most of the nausea that many have experienced by dissolving the huge tablet under my tongue after a meal. I'm also taking Zantac twice a day while on the protocol. I'm hoping this passes soon. There is only so much daytime TV I can tolerate.
