nah this is just withdrawal...when I drink, I go without food for 5-6 days (depending on how long the bender lasts) and then needless to say, the day after I can't eat too...i force myself though, even though i eventually have to throw it up...but step by step and day by day i eventually "learn" to eat again
this spring i went on a two weeks bender, did not eat ANYTHING but a pack of crisps PER WEEK...when i sobered up, i felt like i've forgotten how to chew, it took me a week to finally eat a whole meal at one time!
