My neighbor suffers from almost daily vomiting and has for several years. I don't know her medical history, but I do know that she is on strong anti-anxiety meds for a psych condition, and that in periods of high stress, the vomiting is exacerbated. She swears by smoking as a way simply to keep food down. I recommended to her Hindu Kush (the most anti-anxiety strain I have available) and canna-caramels to dose when she can't smoke, and have been teaching her to grow.
I'd definitely look into caramels or another edible that is a high dosage compared to a small delivery size, which I'd suspect would be less likely to give you a gurglygut reaction. You can melt the caramels in your mouth so you aren't swallowing solid food, and even try taking them in the middle of the night so that you are medicated when you wake up. There's a recipe in my donkey dick grow log somewhere- I think page 5 or 6. You can make the butter using the 'washed butter' technique; start saving yur stems and shake, and if your dealer is a good soul maybe he or she will also save shake for you and cut you a deal on it. That's where I get a lot of shake for cooking- I happen to know a couple dealers who are compassionate towards the medical community and will either give it away or sell it at or below cost.
