Let me know how you get on with the Famvir, if it doesn't relieve some of the vertigo/dizziness then no point in taking it. I've just seen a local GP who's agreed to do some viral testing, sit on the floor with amazement.....so I won't take any until after those tests - have to wait nearly 3 weeks to get the blood taken, NHS at its finest....... I also have some Rfaxamin to take, I thing some of the virus lives in the digestive system too, so having a high bacterial load makes it easier for it to operate there, only my thought.. I have felt better after Rifaxamin, but not permanently so.
