The setting is 2009, in a hotel room in a big city neighborhood that's just this side of "Holy god, why would you want to stay there?", so access to a cheap liquor store is pretty much guaranteed for the character. What I'm trying to figure out is how realistic it would be for this character to be at the 5th stage of drunkenness as described on this page. For the linkphobic, they basically describe it as the stage where incredibly stupid decisions are all but guaranteed, but you can still speak reasonably well without slurring.
My character is early 30s, with a BMI of 20.2 (pretty good for her height, 5'11"). What I'm wanting to write is her going to her hotel room and getting drunk, then doing something incredibly stupid that I'm still working on. This will happen maybe two hours after she started drinking and her drink of choice is going to be either beer, rum, or vodka. Is what I'm aiming for in terms of how drunk she'll be realistic or off-base? If it's off-base, what would be a better way to get to the point I'm aiming for?
