Hi everyone. I am a 21 y/o female, and have been having nausea on and off for the past 10 months. It had a sudden onset last May. It has been very severe at times, to the point where I cannot move or eat without throwing up. It is basically the only symptom I ever have. (Occassionally, I get weakness in one or more limbs, tachycardia, as well as fatigue). I do not lead a stressful life, so that is not a factor. I have been to two different gp's, two cardiologists and a gastroenterologist. I have had thyroid hormone and glucose levels tested through bloodwork, a head CT, a 24-hour urine catecholamines test, a heart monitor, and an echocardiogram - ALL negative! I have been prescribed Nexium, which had no effect. I have also tried Reglan (prescribed by my gastroenterologist), which only made things worse. I am now on an anti-vertigo medication (also prescribed by gastro.), which is making me very drowsy and helping little or none at all. I have three different prescription nausea medications, all of which make me fall asleep instantly, which I cannot afford to do as a college student. Does ANYONE know what this could be??? OR anything I can do to get relief without the drowsiness???
