I have been on wellbutrin for 5 months and iv lost about 15 pounds. Im actually getting a bit too skinney but i like it alot and would prefer to stay this way oopsed to a couple extra pounds on me. I was wondering if i will keep loosing weight and also if it will stay off while im taking the wellbutrin. Or will i start to slowly gain it back? This is a miricle weightloss drug i have to say! yeah, i was running for 3 months and was eating well but as soon as i took the wellbutrin it blasted me in wieght loss lol. But yes i totally agree. Im gangly skinney now. I just bought a 6 month membership to a gym today :) so im well on my way!
