hepatitis c
"I'm 52, female, HIV+, Cancer survivor, Liver Transplant Recipient.
I was one of the people who studied this medication through clinical trials. I tried all the other treatments, but none of them cleared the Hep C. During the trials, a slightly different combo of this medicine worked within 4 weeks. As my liver was already severely damaged, I developed cirrhosis, then cancer, then I had a transplant. After 3 months Hep C was detected in the new liver. I was immediately placed on Harvoni. I've cleared within 4 weeks again! 
I do have side effects. The main one is headache. Then nausea, slight fatigue and the occasional throw up session (which lasts only a few minutes, then I'm fine). 
I do get a dizzy feeling, but it is not a problem at all."
