Here's my two cents worth .... When I lost the first 30 lbs I was not on antidepressants. On antidepressants (and with some other health issues) I gained back 24 lbs. I'm now on paxil and it does seem a bit harder. I'm exercising more, for sure, and probably my calories are consistantly lower than last time. But I am losing. That's my note of encouragement for you
Also, Paxil is my 4th try with antidepressants. If you have side-effects, talk to your doctor. Mine told me there are lots to try, you don't have to keep taking one that adversely effects you.
Also, (I just keep thinking of things to add) This time I consistantly feel more like "doing it". I used to clobber away at diet planning and exercise for a few days and then blah out. Other than being too busy with family things a couple of days, I've not had a down day yet.
