My main concern when I drink heavily is dehydration, not any issues with the pouch.

I have had the Moscow Mule, it's fairly popular.

I attended an informal law school reunion party a few weeks ago and got very drunk mixing Beefeater Gin and Tito's Vodka drinks.  I did not have a designated driver so the host made me stay until I sobered up.  I did get a little dehydrated.

Many J Pouchers worry about the pouch when they drink but really your number 1 concern should be staying hydrated because that is what will make you feel like crap the next day.

My official 25 year law school reunion is October 8 and I suspect I will be intoxicated at that event but it's an all day event so I think I will be sober by the end, but if not, two of my close friends and classmates who do not drink can serve as DD.

I should note that I am on a 2 drink a week diet imposed by my GI doc due to taking Methotrexate, and I only drink at special occasions but when I do I explode past the 2 drink limit.  So far in almost 6 months all my blood tests came back fine and the liver chemistries look good, so the liver is holding its own against this assault which also includes antibiotics.

When I use to drink heavy I made sure to wear depends because I often had accidents from being basically passed out.
