why must I be a hypochondriac?

Okay, so that term might not apply now, but usually I am.
I'm on new medication for my IBS and it's helping my stomach SO much.
It's great. I feel like I can eat anything (almost) and not feel sick, but the side effects are unwanted.
Now, me being a complete google maniac and googling everything there is to know about this new medicine, I've read the following:

1. side effects can take a few weeks to wear off.
2. don't stop taking this medicine abruptly or without consulting your doctor first

well, I've had about 5-6 side effects now, and never on any of my other medications have I experienced side effects to this extent. I'm thinking that it's because this is an antidepressant, even in a low dose. So, I'm going to call my doctor tomorrow to see if I should stay on and wait for the side effects to wear off, or just stop taking it and maybe try something else, or just don't go on another med and have my stomach suck again.

It sucks I can't stop taking it until I call my doctor. I'm not even sure how I could slowly come off of this medicine, since I think that I'm taking the lowest dose there is. 

Man, antidepressants are scary stuff.
