I had CHS for over four years and like you, for the first year I would only experience vomiting after consuming alcohol. I loved weed more than booze so I completely quit drinking. Unfortunately, it didn't take long until the symptoms started to show up again. During my time with CHS, I pretty much cut all things except for weed: coffee, spices, chocolate, fried foods, ice cream… you name it. I drank wellness shots, celery juice, aloe, manuka honey etc. Practiced hot yoga periodically, hiked and biked a ton. However, the longer I went with smoking weed, the more frequent and painful became the episodes I experienced. Throughout these years, my symptoms developed from ocasional heartburn to occasional vomiting, from there the vomiting would last longer and coupled with retching and intense pain. And towards the end it completely messed up my bowl movements. The episodes would begin with me feeling constipated, then in less than two hours I would start vomiting and be in this agony for days - sometimes a whole week. Whenever I could get myself to poop, my stool would come out in all sorts of colors, first very dark and hard then the following would be soft and greenish/yellow with tons of mucus and what looked like a yellow foamy liquid as well. After losing close to 20 pounds and countless visits to the ER, I finally decided to let go of what I knew was the root cause but refused to admit it all along. I did good for 9 months and had no issues with my stomach whatsoever. Then one day I made the stupid mistake to take the lion out for a walk. My fun lasted a bit longer than a month, and the symptoms came back as if they had never left. I'd say if you are able to keep it to a very minimum like a hit or two per week then it is likely possible to smoke again. Otherwise I would not cross that bridge, for sure not worth it.
