Hope you get some useful replies. I haven't tried reta so I can't add much beyond wishing you luck.
Right now I'm on reta at 3 mg weekly. The low dose worked well at first for steady weight loss, but lately I'm not feeling much effect so I was considering going up to 4 mg. My resting heart rate has already climbed about 20 beats though, and I don't want it higher. That has me thinking about switching to sema when I start my next diet phase. What starting dose makes sense and how does sema usually feel compared with reta?
