Every once in a while someone will offer a beer or glass of wine at a campground. But the best way not to come off as rude in declining it is to politely decline it. If you can hang on for a few years it gets easier to just say no without feeling compeled to explain why... Truth is if you just grin and say no thanks, act matter of fact about it and not like its any deal at all there is seldom a problem.

Honestly I once did have some drunk Australians get very upset that I would not drink any wine with them(they were next to me at a campground in a RV). I was able to deal with the jibes by being more entertained at how stupid they were acting and being glad that I was not in the same state.

Sometimes there will be no place to eat but a bar and grill. if your feeling shaky get it to go, eat your last power bar or go on hungry, or else suffer through a burger and leave. I did all these things at one time or another in the first days. I actualy started touring three months after my last drink, as something to do.

If you have a cell phone, try to keep some numbers of people who are supportive. Keep a charge on the phone.

And don't worry about touring overseas untill its time to think about touring overseas.
