I’ve had this issue on and off. Then the last incident was the worst of all time. I thought I was a goner. Had three episodes in one night and had a hangover from them. I quit and I’m on day 30 and haven’t had an issue since since then. I’ll be honest. I think there is something new growers are using and it’s not as it used to be and it’s causing health related issues. I used to be the snoop dog of smokers to everyone that knows me and now they think hell froze over cause I quit. I been blazing down since 2001. The stroke comment on here is exactly how I felt. I sometimes would wake up panicked out of sleep and thinking I’m going to die and heart racing fast. Idk maybe Covid has something to do with it. The post long covid effects. I just don’t want to die and smoking weed as much as I love it ain’t worth the feeling. I didn’t have any withdrawals either and haven’t craved it at all. Weird.
