smoking is definitely a very bad idea. It is highly likely that this caused your cancer. This means that you (and I) are able do develop cancer (bad luck, deficient repair).....
Given this it is not a good idea to tempt fate again.
As far as drinking is concerned. I would definitely stay away from hard stuff. To me this tastes like pure gasoline (2 years out from rads), therefore it is easy to stay away from it. I do drink wine again now and again.
