side effects via internet, several people said it causes weight loss. I was 138 lbs then, A little weight loss I didn't mind, but noted I'd lost over13 lbs. in 2-3 months-stopped buproprion Aug. 2011,it never did anything to ease anxiety & depression, kept losing weight--25 lbs. as of now, Aug. 2013. In June 2013 weight loss seemed to stop, but resumed in a few weeks. All clothes & underwear much too large, was able to take in some seams via sewing machine, my stomach calls for food about every 3 1/2 - 4 hrs., I must feed it immediately, or lose more weight very rapidly. I carry sandwiches, etc. with me to keep from still losing weight, now down from 138 lbs to 115 lbs, getting lower, not sure what to do . Never ever, had this type of problem, except with and after buproprion, still have its side effects, I wonder how to stop these effects. No doctor seems to know, if I eat too much carb, it spikes my blood sugar, at one time my doctor said I was headed for diabetes. Have to be careful how much carbohydrate I eat, even though it's carb that provides weight gain.
