I can usually go either way as far as sleep goes. I've fallen asleep with a bowl in my hand, and right now, at 3:55 a.m., I'm smoking a bowl, typing this. Bud helps me sleep, but, usually, doesn't make me "sleepy", if that makes any sense. As long as I keep my mind occupied, I'm fine, but if I lay down and get cozy, I'm out like a baby. It also depends on what medications I'm on at the time also. Some of my anxiety meds (taken as prescribed) mixed with pot put me on my ass pretty quick.
