i don't remember getting any hangovers or anything from smoking pot, but like everyone else said, your body is probably just new to it.. i know sometimes if i smoke a lot though during the day and night sometimes i wake up feeling stoned still and extremely burnt out.
yeah man, it's just you still high but in my case I forgot how to appreciate it, and in your case you don't know how too yet haha goos luck with everything man, and i'll match a blunt over the internet anytime.
I get them the day after I smoke all the time. In fact I'm feeling it right now. I don't think I'm still high, I'm just lazy and my mind feels fuzzy. It takes a LONG while for it to go away too, like 6 hours from when I wake up. Or I can just smoke and it'll go away.
