jay,
i just got back from my first vacation w/o a drink. not one. shocking for me. i read your posts and they sounded so familiar. all the symptoms will stop. water and multi's are helpful. and support from your freind will definatly help you get thru it. but, remember that when he leaves you will be feeling good and all, about the time you think you can have "just one". DON'T!!!! i did exactly that. i felt sooo bad i couldn't beleive it. back to square one....sucked.
keep posting, it helps
