I increased my Valtrex to three times a day now, started on 4 pills of the maitake mushroom and increased my TF to 2 a day. I have not been out of the house in a week and no one that I live with has a cold. I don't have a sore throat or anything so maybe it is just a mini immune response. My tummy is a little off but not anything too noticable. Any body ever have a mini herx off of somthing?
