I weaned myself off of Sertraline and pursued OTC options just because the brain zaps and the yawns/drowsiness were so bad. Didn't matter what time of day I took it, didn't matter that the dosage was low. The brain zaps made me lose trust in my own faculties. These momentary, split-second losses of consciousness, where after each one, I'd have to spend another split-second reorienting myself to the environment, got way too disorienting. It also got worse the longer I was on it.
Finally weaned myself off and use SAM-e instead. No perceivable side-effects there. For anyone who doesn't know, SAM-e is an OTC supplement in the U.S. but the same chemical compound as one of the front-line antidepressants in Europe.
