Um, you should BOTH speak to your pdocs, like, Yesterday!
Seriously, quitting an anti-psychotic is not the best idea when you are doing it without a pdocs help. Things tend to go down the drain really fast. If you are already having symptoms then you know, for 1 thing, the drug was working. Work with your pdoc to find one that doesn't make you sleepy, or see if your dose can be taken at night. Or find out if there is something you can do to counteract the sleepiness. I'm in the middle of that fight myself, so I understand it's a tough, tough battle. But seriously, guys, is it worth losing your sanity over?
