Usually one a day, more on the weekends. I think that puts me at about 10-13 a week. Though, between now and may 10 I'm probably going to be cutting back. I have loads of work between now and then, and since I'm moving on the 10th so I won't have enough time to age and drink another 5 gallons before then. So sad!
Fun story: a few months ago my school subscribed to this BS alcohol consumption quiz/website/thing. I filled it out just for laughs (being 100% honest, mind you). Apparently, I drink more in a week than 93% of college women, they calculated my tolerance factor to be 270 (the chart only went up to 250) and my averagee daily BAC is enough to where I should be blacking out regularly. That was a good laugh, glad my school wasted their money on it.
