What medication are you taking? And wow that sounds like a lot to drink even for someone who is NOT on medication!!! All I can tell you is that you really do need to monitor your drinking. My friends rarely let me drink, so I usually have a beer and then switch to water for the rest of the night and I feel great (currently on 10 mg of Lexapro and .5 mg of clomazapam daily). But yeah let me know what you're taking. I'm curious.
