Just to add another no vote...I tried it a few times; you're going to need something to occupy your attention; like building a house or something. Otherwise you can pick and/or vibrate yourself to bits. I'm lucky in that I'm a compulsive builder of things, 2 sticks and a piece of string would occupy me for hours. I found that an outlet for the meth high, like making guitar effects, was the only thing that made any sense out of doing crystal, and stopped doing it right away, anyway. I heard somewhere that the nazis developed it for long-distance bomber pilots and other such nasty trades, and it sort of figures. Don't go there.
