This is the thing...everyone's healing is unique, although we all share some similar experiences. I would suggest starting slow with alcohol. Remember that your upper GI tract has been through a lot. Still, sip away, and see what happens. Listen to your body. If it says, "Okay! It's fine!", increase the amount. Still, I suspect you'll want to keep amounts you drink smaller than usual. It's really a trial and error thing.
Hopefully it'll go well and you can enjoy a little alcohol very soon! By the trip, you'll be farther along, and that should help.
