Replying to I got TOO high?

So on Friday, I got high for the first time. It was chill, had to hit the bong multiple times before I actually felt anything, and when it hit....holy fuck was I high as hell. So the rest of the night, we chill out, go to McD's, get some food and chill out more. Then I go home and go to sleep. When I woke up this morning, I had no idea what the fuck was going on. Like I just could not think, time seemed to be going really slowly, and I kind of just chilled for like 3 hours.

I'm just wondering, is it possible to be high for 10 hours like that? Or did that kush have some extra cheese in it? And by cheese I mean lead or something fucking equally strange. Have any of you guys had a similar experience? Or was it just because I went to hard since it was first try friday?
