Today I went Disc Golfing with my sister, her husband, and one of their friends. I hadn't smoked in two days and kinda enjoyed being sober. Being high wasn't fun anymore and I was thinking about quitting. We stopped at McDonalds, and I had two McDoubles which tasted like steaksauce. After we were done eating, we left to go play disc golf. We played two holes and lit up at Hole 3. We smoked two bowls, and we waited for a couple people to play through. I started noticing these weird visuals. I loved it. I was too high to play, I knew it. Everything was extremely bright like there were a thousand suns in the sky. I wasn't squinting and nobody else thought it was brighter than normal, so I knew it was all in my head. I don't remember, but I assume we were letting some more people play through. At that point it was extremely bright. I lost my vision. There was some blotchiness of vision poking through the whiteness I was "seeing". I don't remember standing up to get the discs we through, but I kinda remember hanging on to the sign that marked the hole and collapsing into a bush. I blacked out, and my sister who was in front of me came over to help. I said I was fine and walked a few feet and blacked out again. Everytime I blacked out, I had these intense dreams about hallucinating. There wasn't like a story like most dreams have. There were just these visuals on top of the whiteness. Everyone was talking to me asking what happened and I was fading in and out of consciousness. They asked me to count, and I did that fine, but I counted really slowly like I was brainwashed or something. I fell unconscious again and started moaning and my leg was twitching. I had never had a seizure before, so this was a new experience for me. I was breathing normally, but I had a slow heartrate. They picked me up and sat me down on a bench. I don't remember much after that. I snapped out of it once we were in the car. Then I was just high. My sister told me we were going to my Mom's house. To let her know what happened. My mom called my dad at work and he came over. She told me to lay down and sleep to sober up. I woke up a few hours later with this huge migrane. It felt like I had a brainfreeze. I'm in bed still. I'm sober and migrane free. I'm just drained. I'm done smoking. Tl;dr I went to McDonalds, played two holes of disc golf, smoked two bowls of medical, started tripping, blacked out, had seizure for first time, started fading in and out of consciousness, went to my Mom's to sober up and got a migrane. My tolerance has nothing to to with this. This experience was nothing like a low-t trip. Nobody else felt anything unusual either. I'm not sure what happened, but it was embarrassing and I feel bad for ruining everyone's day. (EDIT) when I was put on the bench, my face was pale and my lips were white. I was also sweating uncontrollably.
