I only snorted one line at a party with some friends. We smoked about...2 oz. of pot, though. So, the comedown was fine, and I was able to sleep fantastically that night, still. I usually have insomnia and I thought I wouldn't be able to sleep for DAYS. But, I passed out as soon as I got home. It was great.
Anyway, yeah. I was the same way, but it really leveled me out. It didn't make me extremely hyper or anything. I was actually lethargic, and EXTREMELY happy and accepting. I had this smile on my face for hours.

Two friends though...they went NUTS. They both got naked (well, sorta. the guy got naked, the girl got into her bra and panties) and ran around the entire farm of the friend's house. Then, they came back, and had a shower (with him still naked and her still in her skivvies and such). He ended up having her shave his armpits, and they took all kinds of photos of them "modeling." It was hilarious shit.
