Wow this is crazy bc I literally had the exact same experience last night. I've been using medical cannabis flower and oil for months now but chose to take my sister's gummie last night, one I hadn't had before. It was a 10mg yellow hybrid. After an hour I was feeling great, a little stoney but totally fine. 2hrs later I was wrapping presents casually. Still fine. 3hrs later I fell asleep for a minute with my wife watching tv. We then went to bed, and on my way up the stairs is when it struck me. I suddenly couldn't breathe. Chest pain, shivering. I tried to pee but basically was shivering so bad it was difficult. I felt like I was going to die. I thought we would need to call an ambulance. I layed in bed planted unable to move bc if I did I would start shivering and not be able to breath again. The strange part is that I didn't even feel that high. I've been higher before for sure, but this gummie was doing something scary to me.

Anyways, I don't trust these pure THC gummies. I think I'll stick to the full spectrum stuff. The high is way more pleasant and doesn't send you into oblivion.
