Eat a little something every 2 hours, lots of juice, maybe a multi-vitamin, get a semi-boring book to put you to sleep at night, stay off the happy pills, don't smoke dope, prepare to sweat some so maybe keep the room cool, asprin or the like for some aches and pains.
Figure it'll be like the last few dozen times you didn't drink for a few days, whatever that was for you.
For me it was like a mild flu bug, not a huge deal to get through. No drama involved.
