Here is what Dr. Dietrich in our expert forum says on the subject

Can't speak for him, but based on what he said in the link I just gave you, my guess is he would say continue on full dose. By the way, are you undetectable and if so at what week? Also, what's your genotype?
It's good that you're seeing a hepatologist, book from someone with experience there -- I've seen at least a half dozen over the years -- they are certainly not all created equal. Could be wrong, but it sounds like this fellow is a little too quick to pull the trigger. Perhaps, you want to find a more aggressive hepatologist. On the other hand, there may be other factors involved, so again this is just a general statement.
Good luck!
