My doctor put me on Wellbutrin a couple of years ago after I quit smoking and had put on a lot of weight due to things like being on steroids for over a year for RA and having radio-iodine therapy on my thyroid which threw me into hypothyroidism. Anyway, he said that a side effect of it was helping with weight loss and with the smoking cessation. I had already quit smoking, so who knows if it helped with that and I don't think I really lost any weight until I started dieting. I still take it, but I have no idea if it really does anything to help me. I've thought about stopping it just to see if it makes a difference.
If it helped you lose weight the first time around I don't see why it wouldn't help again. It's worth a shot.
I was on the Atkins diet from July 2011 to October 2012 and I lost 73 pounds. October 15, 2012 started WW's and got down to 255. Gained 25 pounds through the holidays, but got back on track June 2013. Got off track through the holidays again and gained back 10+ pounds
I will continue my journey to the end, no matter how long that takes.
