I've experienced this every time I've taken medicine; The symptoms usually outweigh the benefits of taking them. It's give and take really...
All the meds really do is suppress your illness so that at the very least you can function properly in life.... and that's only maybe, if you find the right ones.

I quit taking my meds over a year ago because of the bad symptoms they were causing and I'm caught in-between struggling and "normal" but now at least I don't constantly feel sick and groggy...

oh, and some meds cost a lot if your insurance doesn't cover it, yah... you might feel some piece of mind but if your'e always broke because of your meds then it's not worth it in my opinion, I hope I helped a bit.
