Hi have been on Harvoni for two weeks today. I had a little bit of 'dippiness' and slight headache for the first few days but this resolved. This last week, however, I have developed nausea and severe diarrhoea - to the extent that I have cramps and have to get up several times during the night. Has anybody else experienced this? While one can expect early side effects right at the beginning of any treatment that will usually improve, I'm worried because this is starting 10 days in so might be an ongoing problem? If so, does anyone know if it might also affect my absorption of the Harvoni tablet?
