i have been on welbutrin (bupropion) hcl (xl) 300 mg for about 5 years now. just don't feel like it is really working for me anymore and am experiencing weird tics and seizure like symptoms during the night. kind of scared about it and was thinking of talking to my dr. about switching to topamax. just really scared to make the change as i do suffer from depression and weight issues. not sure as to where to start dosage wise (guess the dr. will know better but thats debatable with mine). would love some input from people that have made that switch. also was thinking of adding seroquel but from what i have read its a weight gainer. no thanks. maybe i will try trazadone.
