Beer Sleepy

How to avoid sleep?
When my girlfriend drinks a few beers get much sleep, what can you do to avoid drowsy from few beers?
drink caffiene breast, eat some caffiene, or if you really need take some pills caffiene. Sells Bawls mints and drink caffiene (Tastes yells a lot, but is a bit expensive). I know a friend who also gets tired when drinking, and is placed over it by drinking a lot of caffiene. But then crashes quite difficult later in the evening. (She says it's better than being tired all night)
Sleepy and el Jefe try and fix the lawn mower.
