I took about 5 hits from my moms indica weed pen. I didn’t even feel anything and then all of a sudden I’m sitting down and my heart felt really fast like I was gona have a heart attack or something and I had to talk to myself out loud to calm myself down and go get water from the kitchen. When I got in bed I was freezing and shivering almost kind of felt like I was having a seizure. I took gaba, inositol and choline vitamins to slow my heart rate down. After that I start some really powerful self improvement talk telling myself to stay strong and that I’m proud of myself. Then I got really creative and started to write everything down and I didn’t fall back asleep until like 3:30-4 am. Is this normal? How do I prevent the heart attack part from happening?
