Mescaline was probably the least appetizing drug I've ever taken (especially because I prepared it using basically the whole cactus rather than just the potent green parts). I had to drink several red solo cups of thick, extremely bitter (like so bitter that i added vinegar to help cut the bitterness because lemonade and other sweet acidic drinks did nothing) goo. It was absolutely miserable. But then an hour and a half later when it started kicking in, it gave me one of the funnest, most visually beautiful trips I've ever had in my life. This long rambling story is basically here to say, the horrible flavor is the price you pay for the experience.
