I got pretty high my first 2 times, like the first time I had serious giggles, not to mention the munchies. And I got a bit of a physical high too. However, I didn't get REALLY high until my third time. I knew it right away when I was in IHOP with some friends and I couldn't stop laughing while we were ordering. Aah, good times. (I'm stoned right now

)
EDIT: My friend showed me how to do it before we went toking. That probably helped a lot.
