Just like they say in AA, stay away from old playmates and old playgrounds. Beer and coffee were my worst triggers. I eventually stopped drinking altogether. I played with some bad stuff over the years and never got addicted but nicotine has proved the hardest mountain for me to climb, though not for lack of effort. I totally agree about the beer. I never understood how an ex smoker could pound back brews and resist lighting up, but addiction is a tricky thing with no hard and fast rules. I did know a guy however that only smoked when he drank.
