Celexa (like many of the SSRIs including Prozac) can cause changes in appetite. Paradoxically it it may increase some folks appetite, but decrease others. Wellbutrin is more likely to decrease appetite, which is why the recommend that people with EDs avoid it. Obviously many people with EDs seek it out because of this recommendation!
I will stress that everyone is different, and I will also point out (despite the bells and whistles that the manufacturers blow on their own behalf), that even the "best" antidepressants only have a 30-40% success rate above the placebo effect. This means that 60-70% of the people given an SSRI will either not get benefit from it (only side effects), or they improve, but would have improved even with out drug intervention. Don't expect miracles in the first few weeks of SSRI treatment. Or maybe you SHOULD expect miracles since the placebo effect can be so strong (if you believe in the drug enough) that it can lift you out of your depression.
