you made the classic mistake, i have myself any many before you. you gave up a med that was working because you thought you didnt need it. Then bang out of nowhere you back in even deeper , Never ever give up something that is working , leave well alone. Lots of people take meds all there life for some illness or what so why the big upset at a AD. NOW if like me your prozac wont work again second time around, it may it may not, but if not move on to another ssri seeing they help, like sertraline or lexapro , you can straight tapper if prozac fails so no start up effects to worry about. And when you get back on track stay on your med, because if you had depression a couple of time ,you will get it again.
