I use psychedelics to open my senses and mind. alcohol does the opposite, it numbs and desensitizes, and creates negative thought patterns.
I used to drink beer every day, and love to drink on lsd or mushrooms. Like 12+ beers, whiskey, whatever.
But I've found booze kills my trip, lowers the visual and sensual effects and brings me down to a lower plane.
It may make you more comfortable and fun until you start detoxing, but it's taking away from your psychedelic experience.
I used to always say, "man the trips don't seem as profound as when we were in high school." I'm pretty sure it's because we weren't drinking back then
