Alcohol intolerance

Greg just made a batch of great margaritas.

I remember a time when I could drink a lot, but now it doesn't take much to make me feel it. With fibromyalgia, I really pay for it the next day. Tequila seems to be the worst.

I used to have a VERY HIGH tolerance for alcohol, but not anymore. What happened? And when did it happen?

It's a money-saver. Don't need to spend as much on drinks as I used to. Does that make me a cheap date?
