I was waiting for approval from my insurance company and found out it didn't go through for the name brand Valtrex. The generic was giving me very unpleasant side effects. I had a three day supply and tried it . I felt immediately funny and end up with head pressure and a vertigo attack. I guess I'm too sensitive for it. I'm going to try my best to get a script for acyclovir . My doc had said that was too high of a dose but I will try with my Ent or I don't have any other way to get it. Doctor gacek doesn't take my insurance and I can't afford to pay amount for the visit and separate amount for treatment. I contacted the clinic and got the price. My luck is running out.
