hi, for the past year i have been experiencing severe vomiting. i have noticed it happens when i dont get enough sleep, however i have insomnia so it happens a lot. i have been to my doctor and they have tested me for everything from thyroid diabetes etc to celiac disease (and everything else you can think of) but nothing is showing up. i had a camera inserted into my small intestines and that showed nothing up. i have had scans etc and nothing shows.

i have fibromyalgia and endometriosis for which i am using fentanyl patches 50mcg the 72 hour ones.

i find i cant keep anything down including liquids. so i take my anti sickness meds (cyclazine ?Sp) but they dont work. i have tried various anti sickness meds and none work as soon as i swallow them i vomit them back up.

i have been using the fentanyl for over 2 years now but the vomiting started exactly 1 year ago today. i have lost over 3 stone in weight and look and feel terrible. do you have any idea what could be making me vomit?
