As for me...
I had a glass of wine at the steakhouse a few days ago. That's about my limit at a sitting, and it's almost always at a fancy restaurant. It's supposed to be good for your heart, but I need every brain cell I have.
My main problem is I can never remember which wines I like best. Oddly, "white" doesn't seem to be specific enough for most places. I should write it down when I get a good one.
