Girl wants to meet for drinks but... I don't really drink WHAT SHOULD I DO?

I go to strip bars and drink soda or sparking water. The more I drink, the more tried I get--then I need more sleep later on. Screw drinking, I like crashing around 3am and waking up-8-9 am feeling refreshed.

I used to enjoy drinking but then after one too many close calls for dui or acting like a drunken jerk too often, I took a 8 month break-cold turkey, for my 25th birthday. That was 20 years back now, haven't been drunk since then. I drink one beer, it seems OK, I drink another beer and feel tried--doesn't taste that great either. So why keep drinking I ask myself ? Just cause everybody else is ? I act crazy enough sober
