and I am REALLY hoping to not have any issues.
Hobbers,
hope is good but pretty much useless when it comes to this kind of stuff.
planning is better.
plan what to do IF you suddenly get ambushed by craving and think you can have just one.
plan on having your own transportation out of there if it gets too much, so that you can leave any time.
plan on what you'll have in your hand to drink instead of a beer bottle.
plan on not going if you start feeling really iffy about this and start hearing any voice that speaks of "last hurrahs" or any such nonsense.
plan on having a good time once all the other plans are in place.
