Hey! I'm so sorry to hear this, GI issues are not fun. I actually have just been going through some withdrawal symptoms from venlafaxine/effexor which is an SSRN, and those withdrawals cause lots of stomach issues. It's almost been debilitating, but it's gotten easier to handle as I've been getting better.

I definitely had trouble with being able to wait to eat while I was on my medicine. If I didn't eat right when I was hungry, my stomach would scream at me, which isn't normal. I also had a friend on prozac who sort of dealt with the same thing. It's okay for your body to be hungry, and these GI issues that we go through getting on medicines and then getting off are so unnecessary and not normal!!
