I think I drank too much alcohol in the last couple of days with too little sleep?

Two days ago i got really really drunk and the last two nights i drank a a little (two to three shots of rum) before bed getting about 5-7 hours of sleep each night. Now i feel kind of faint and my eye is sort of twitchy is this really bad or should i just get some sleep and not worry about it? Is anything really bad going to happen, I'm afraid to fall asleep if it is. Could anything really bad happen in my sleep? Also I have a moderate tolerance for alcohol and a I'm 5 10' and weight 135 lbs.
