I was on phentermine and lost about 20lbs. My doctor switched me to contrave as well because it? seemed I had hit a plateau. I've been on contrave for about 3 months now and now weight loss. I've been exercising and eating right, so if any one has any suggestions, I'd really appreciate it. The only thing I'm losing is hair, everytime I brush/wash I get quite of bit of hair loss. Anyone else having this issue?
