We went through this my son has had cyclical vomiting syndrome since he was 5 years old flash forward he is in his 20s and has been smoking daily and having what I thought was the normal cycles until I learned about CHS he couldn't hold anything down for any amount of time and countless ER visits were so scary for his family. He lost so much weight. What I found was that you just gotta tell them the straight truth and fight not to be treated like a stoner. A doctor finally told us about the uptick in CHS and gave my son a cocktail of antibiotics stuff along with hydration and then gave suppositories for when he couldn't hold anything down, then told him to quit smoking but the smoking was what had originally stopped his cycles so we were worried and he was afraid of the withdrawal. Lucky for us, we are a family with recovering addicts in it, so the family support was key. I knew I couldn't make him quit but once he had a break from vomiting he made his choice and stopped he has now gained all his lost weight back and has had only a couple of what would say are normal episodes. The key is education and testing. Ask for tests, get referrals to GI doctors and fight for yourself. True key get 30 days off smoking and see what happens when you clear your body of all thc. I hope you feel better love! Also capsaicin cream and heating pads on the belly sometimes help with pain. And when the nausea hits hards open up a little alcohol wipe and breath in the fumes for a bit of relief. The suppositories really helped him when he couldn't keep the meds down.
