you are on the right track and have a positive attitude. you will get through these first few days.
sucks being in bed, sick.
worse being in ER... (been there).
worse being in jail (would eventually get there... yeah, i never thought i'd do half the things i've done while drunk).
hang on for the next few days. it will be unpleasant to say the least, but it will be worth it. drink. eat as much as you can. sleep as much as you can. and you might recover faster. don't put too much pressure on yourself right now. take it real easy.
