My old girlfriend used to get a really bad comedown when she smoked. Including puking, chills, fever like symptoms. I was convinced she was allergic to THC. It could also be a really low quality strain. What are you puffing on?
This happens to me all the time no matter what strain it is and it's probably why I don't smoke all the time, meaning everyday, because if I smoke and get even remotely high I'll be ae to sleep forever.
Just the other day I slept for 13 hours just from being high for 3ish hours. It was ridiculous and super annoying because I had shit to do. I'm not sure how to get rid of this, probably smoke more though, as ironic as that is. I know people that will smoke a couple bowls every hour and they don't seem to crash as hard as I do, but perhaps I'm wrong...who knows...
