I knew somone who was a heavy drinker for years and then one day he stopped for a long time, because he wanted to lose weight. He was going on a cruise, so he decided he would drink on the cruise and stop when he got back. He did just that, partied very hard on the cruise and when he got back, he stopped. 3 weeks later he died, because his heart gave out, the doctors speculate it was the stress of drinking heavily, stopping, starting and stopping again, but that is only speculation.....
I know where you're coing from, if I was going on a vacation I would want to drink. When you are on vacation we tend to do things we normally don't do when we are not on vacation, so it gives us a break from everyday life, but with drugs and alcohol, I don't believe it is that simple and things can get rather complicated down the road
So I hope that you weigh the postive and negatives about what this will or will not do for your life and decide if it is even worth it.
