MF, I agree 100% with the comments above. Sparkos hit the nail on the head.
Business trips to foreign places are the worst. Especially if you are on your own.
No disrespect: You need to get your choice right up front. Am I going to drink and behave inappropriately or am I going to have a shot at being sober? I've just been through that (and Sparkos too) and it took quite a bit of planning and willpower and whatever else you think will keep the monster at bay. The pressure can be, and most likely is, enormous. But it can be done.
There's temptation all the way, Mate and you need to put your desire for sobriety almost above your Client's requirements. It's tough, but it can be done. ANd the good thing is (ironically) the more you practice, the "easier" it will become.
PM me if you want some of the plans I tried. Not saying they work for everyone, but I got out of there in one piece and am actually looking forward to the next trip.
Strength, and keep posting.
All the best,
Bruce.
