Me too! It is a paradoxical, unhappy side effect. Painful and frustrating.
I went on Paxil in '99, and have since gained 50lbs....... I'm tall (5'10"), so I had been quite comfortable at my pre-Paxil weight of 170. A bit rubinesque, perhaps, but come on, I'm not trying to maintain birth weight....
While on Paxil, I didn't change my eating habits - kept eating my dear carbs - nachos, garlic bread, beer, you get the picture...
I've since switched to Celexa (last two months) and started LCing and exercising about a month or so ago. Didn't see much, so I went on strict Induction and I'm now on Day 11 with a 12lb loss so far.
IT IS POSSIBLE to lose weight doing LC while still on SSRIs, I'm just not sure how much yet!! But I'm hopeful!!!
PS> here's another bonus - my moods seem to be VERY STABLE since starting LC. Calmer, happier, more focused. I'm sure the exercise is helping too.
We can do it!!!
