skee is right when he said drinkin before a gig is jus a false nerve...me personally ive never played drunk on stage in my life and probly never will...mainly cuz im scared ****less that ill screw up.. but i must admitt i have smoked mary jane before a show plenty of times, but smokin weed is a totally different thing with me then drinkin.. i am a "pothead" so to say and ive learned how to control it, so that it only influences my playing(but im one of the lucky ones, where as i dont get nervous before a show)...but then again i do think there is nothing wrong with drinkin and thinkin of songs in your head!(then later on perhaps record them by humming the melody)...sometimes it works! but sometimes you listen back when your sober and your left thinkin "what the f*ck wass i on???"
