I was GT3, and got myself treated with Sof+Dac from fixHepc back in November 2015. [Million thanks again to Dr Freeman!].
I have reported quite a lot on alcohol consumption during sofosbuvir-based treatment. You can use the forum "Search" feature to look back on previous posts about this from me and several others.
Basically, I drank alcohol moderately (more than you report) all the way through treatment and I am now still HCV free. Here is my report from 9 months ago:
OK, it was a scientific experiment with N=1 (one person), so not statistically significant. But I was so convinced it was the bug and not the booze that was messing up my liver, I went ahead and did it just to try show that alcohol consumption is a false argument to deny treatment. End result, alcohol had absolutely no effect on patient outcome (N=1, but I am sure I am not the only one).
For a healthy person, 24 units per week is not excessive. For everyone with Hep-C, the health priority should be to kill the bastard bug first. Then look to the booze if you still have a health problem.
