Anti-depressants are very much tailored to the individual. What works for one may not for another. If you have specific concerns (such as weight gain or sexual dysfunction), they can "tailor" the appropriate medication to meet your needs. Not all of them work the same.
At one point, I was on Paxil, Prozac, Wellbutrin, Topamax, Luvox AND Abilify. Not quite all at once, but close though. (I had VERY bad, long-lasting depression after discovery, which was exacerbated by a family history of mental illness, so don't be afraid that such a thing will happen to you. It's VERY doubtful.)
Side effects are hard to pinpoint, because each medication will work differently for different people. For me, I tolerated Prozac very well - but Paxil made me a zombie, while Topamax made me lose my MEMORY. (That was scary. My XH told me that I had chased him around the kitchen with a knife, and I have NO MEMORY OF DOING SUCH A THING.
)
Again, don't let what I'm saying scare you. The moment you experience side effects that you don't like, you call your doctor and they WILL change the medication to something that will work for you. It does take a couple of weeks for the meds to kick in, though (especially if they're SSRI class - Paxil and Prozac fit into this category), so you may have to give it time to work.
I know more about this subject than I want to know, believe me.
Good luck. It WILl be okay, no matter what you decide. It does get better, though it may not look like it now. But it does.
