I finished my Harvoni med 3 months ago, and lab works shows Hep C all gone, yippee! But, I have noticed some changes now - have gained about 10 pounds, cannot get it off, and I have always exercised and ate healthy. Also, things seem to irritate me so much faster now, and I've never been one to complain about life. Have any tests been done to see about any lingering and long term side effects?
