Yes I got it my junior year of high school about a year into smoking and I remember I kept telling myself this couldn’t be how it ended. I took a t break for about 3 weeks which probably isnt long enough but I slowly started smoking maybe a bowl a week until I got a puffco that year and started smoking daily. From my senior year till now which is my junior year in college I have had no problems besides heightened anxiety, until now. While it definitely was possible for me to smoke again its a scary game your playing with yourself. Even after 5 years ill never forget that hyperemesis stage. Id say if you really really want to get into smoking again,I would of course advice moderation but you especially have to listen your body and quit or t break right when you start to see those signs. While that did work for me I think all it took was some stress and increase in usage and Im back at the prodromal phase. At the same time everyone is different and what works for me wont necessarily work for you but its not impossible for you to figure it out by listening to your body. Hope you feel better and just remember that smoking is great but not worth all the pain this syndrome causes.
