Ya liqour before beer you're in the clear, beer before liqour, never been sicker, is a good rule of thumb. Sometimes I like to mix it up but mixing too much, and mixing the hards too is a good recipe for puking.
Most people I know in "the drug scene" aren't too fond of alcohol, but alcohol will always have a place in my heart, so many types, so many ways to drink them, in so many places. Like all drugs it's all about context, where you're getting drunk:
Beach - lighter smooth beer like corona
Bar - Pitchers of Canadian, kokanee, shots of jager or appeltons 151
Club - total mix, whatever's going on
Camping - Keg and a 40 of vodka
Special occasion - tequila, scotch, good wine/port/champange.
By myself, alcoholic style - a bottle of cpt morgans spiced rum.
