Tried those things a few years ago. It's actually a fairly interesting concept. Now, the one problem is that they somewhat work on the premise of being a placebo, in the way that they only work if you keep your mind open to the possibility that they will work. They fuck with my mind a decent deal, but nothing like one of my music teachers, he tried the "i-doser" for "Heroin" and...well... He didn't remember how he got from the cafeteria to the music dept... He also had no idea what the words written on a piece of paper he had meant (I don't remember what they were).
The Alcohol one also had an effect on him. He's a trumpet player, and any good brass player can tell you beer is awesome, because when you're practicing for a while, your lips begin to ache, once you drink a beer, the lip muscles relax, and you can continue practicing. Apparently the alcohol i-doser had that effect on him... As far as I go, it throws my balance out of whack.
