I am a 20 year old woman weighing around 120 pounds and I drink casually, a couple times a month. The other night I had 6 drinks (1 shot of bourbon, 5 cans of beer) over the course of three hours and I started throwing up. In the next 45 minutes I could no longer walk or talk and I passed out and was carried into an ambulance by paramedics and taken to the hospital. I often throw up the night of, or the next morning if I have 2 or more drinks. I know 6 drinks is quite a lot but it was over three hours and this seems like quite an extreme reaction, when most people would just be fairly drunk. My family also has no history of alcohol intolerance. Any ideas? Thanks
