LexiRae I do hope you have been working with your Doctor on this problem, vomiting allot is not good for your throat or any of the tissues that connect the mouth with the stomach, and it can cause some severe problems. There are allot of new drugs on the market that they use on Chemo patients that help with nausea and vomiting, cancer patient have really bad problems with it because, most of them are on some pretty strong pain meds, and then add to it the chemo therapy! Anyway this has been along time ago, but I know for some of the really difficult cases, where nothing seemed to work to stop the nausea and vomiting, allot of the Onco Doctors would prescribe Dronabinol, and it had a pretty good success rate. It is by prescription only but you might want to look it up and then talk to your doctor about it. Some people just have a difficult time with taking pain meds, my daughter is one of them, but allot of the times it is just dose related and you need to be started off on a very low dose and then gradually increase the amount till you get to the effective dose. It doesn't sound like that would work your case but if they haven't tried it yet, it might be worth doing it. Just a thought???
I do hope you can get this resolved soon, keep on your Doctors to find a solution, as it is not just important to your physical health, but it must also be very difficult to cope with!
Good luck to you!
