I am a pharmacist, and my first concern when taking any medication is whether or not it is going to make me n*. Lexapro/Zoloft/Celexa/Prozac do not normally cause nausea. I always tell my patients to take the medications before they go to bed, so if they experience any n* they sleep right through it. Hope that helps I am on Prozac and Lexapro and do not have a problem with either.
