Thank you Christine. We looked into any changes in what ive been doing. It might also have something to do with trying to stop taking the pain meds. I thought the fentanyl patch was working well, so i stopped my percocet. This could be causing withdrawal symptoms, such as the nausea and vomiting. Last night we decided to try taking the percocet and then push through with the boost drinks. If i vomit, i vomit, but at least im getting something. This might have been the culprit. I have yet to vomit, although a little nausea remsins, but im keeping it down. I didnt think i would be so dependent on the percocet. Its kind of got me worried about the fentanyl as well, since both are highly addictive. So, right now i am trying to go back to the percocets every 4 hours as was prescribed, and trying to take in as much nutrients as i can stand. I was pretty fearful of having to go to the ER. It looks like i might be able to avoid it. Although still, going to check in at the cancer center in the morning. Thanks again.
