Not since college.
I almost never drink, except on rare social occasions. That's partly because I'm gluten-intolerant, and most alcohol is made from gluten-containing grains, but also partly because I just never enjoyed it much; I don't enjoy the feeling of being drunk. When listening to music, I want to enjoy the music to the fullest, so why would I want to dull my senses and impair my full ability to savor the sounds? Makes no sense to me, but then again, a lot of the things that a lot of people do, don't seem right to me. That's okay; diversity is what makes life and society interesting!
