Good luck with it. Alcohol definitely seems to be a component or trigger at some level for many people. Maybe it's a candida thing? Maybe around the time you started to smell you were put on some heinous Antibiotics and didn't associate one with the other at the time? No idea really.
At this point, the first place to start would probably the doctor to get your liver tested out. If you've gone to the same doctor for a really long time, or have access to them all, it might not hurt to request your medical and prescription history from before the time you worked at the bar.
