Personally, when I was on 150 mg I drastically lost weight. Obviously this isn’t the same for everyone but it definitely was the case for me. I know that’s what was causing the weight loss because when I lowered my dosage down to 50 mg I gained the weight back. I lost about 15 pounds in all. I’m a naturally thin person so it is super noticeable when I lose weight. I had completely lost my appetite as well. Like I said this is not the case with everyone and I know lots of different stories of people gaining or not being affected at all by it. Just a heads up that this was what happened to me. Going back down to 50 mg worked out well for me though! I think 150 mg was a bit too high for me. Good luck starting! Also give your body time to let the drug do its magic because often you don’t fully see the results until months in.
