Harvoni leaves the body through urine and feces not perspiration
Keep up your normal life unless that includes alcohol. I would avoid any supplements while on treatment as well.
It would have helped if I read your entire post. But I also did cardio (treadmill moderate to quick pace) for a half hour per day...
You're not going to sweat out the meds...
I lifted fairly heavy throughout the duration of 12 weeks on Harvoni and it din't have any negative effect on the outcome. SVR12
One word of caution, Harvoni has been known to raise blood pressure in some people, me being one of them. As you're probably aware, lifting does spike your BP and if it's high already, you may get to the danger zone.
Good luck.
