Welcome back sameold. Glad to hear you have some concrete plans to try something different this time around - that's really what it takes. Luck really doesn't help so much when it comes to getting sober I've found - but hard work does.
Perhaps before you go you could put together a sobriety "survival"kit. Maybe some books on sobriety/self improvment, some healthy snacks and drinks, etc. If you are thinking of giving AA a try the big book would be a great one to stick in your suitcase!
