"i&#039;ve been on prozac for 2 years for post traumatic stress disorder, in may 2012 i had gastric bypass surgery and recently went back to my doctor because i felt like i wasn&#039;t even on my prozac anymore (i wasn&#039;t absorbing it after surgery) so he doubled the dose. after 3 days i felt way worse! so we dropped the prozac back down and doubled my topamax. the combination of topamax and prozac made me feel awful! i had uncontrollable crying, bad nausea, and was probably the most depressed i&#039;ve ever been. i was diagnosed with a mild form of bipolar, so we started on 50 mg of lamictal for 3 days then we bumped to 100mgs. its been 5 days, but i can honestly feel a difference! haven&#039;t cried since, feel better mentally and i&#039;m just happier."
