When I come down my eyes burn, but otherwise I usually feel pretty good. I never feel negative at all until it's out of my system. Even when I have fear, it's not associated with a negative emotion.

The one time I had a bad trip, I would profusely sob for just a few seconds at a time, which felt like minutes, but I had a clock, so I know it was just a few second. But even then I wasn't sad, it was like an automatic response in my body that was getting triggered for some reason, it had nothing to do with what was going on in my head.
