No, it's not too soon to feel negative side effects. Actually it's common to feel the side effects before the benefits. I actually feel side effects after 2 hours of taking SSRIs. Not to worry there. If you're worried about the actual side effects you're having, I would suggest contacting a doctor or pharmacist.

Best of luck to you!

On the plus side if you're having side effects, that typically means it's working.
