I would have to say that I did tend to black out less after drinking beer only. It got to the point of only cheap Vodka would do. After 4AM the stores would stop selling & then I resorted to household items, mouthwash, ect... On occassion though I would down a case of beer drinking from 7am-10pm.
I also drank beer sometimes at bars because it was cheaper, of course, I had a pint of vodka in my pocket as well.
