I am sorry 10sboi that you didnt get any responses from your post here. I cant speak for being able to lose weight while on this medication as I havent ever taken it but, there are many people who report weight gain while on the XL I know. Perhaps if your having some weight management problems try talking to your physician regarding this to see if there isnt a different med to go to with lesser effects or maybe they can give you some ideas on what to do.
Please do feel free to post as often as you like, usually we are quite informative. Take care, and welcome
