Alcohol is a diuretic (read: dehydration) which lasts for quite a while after the acute effect wears off.

I avoid it the night before diving for this reason, as dehydration is a known risk factor for DCI. I also avoid caffinated coffee, although this may be more of a wishful thinking thing since I am a fairly serious consumer of diet Dr. Pepper (and cola drinks contain caffeine, which is ALSO a mild diuretic!)
