I am a 20 year old female, and I've been bulimic for years now. I only usually throw up after large quantities of intake ( binges) but have learned to keep smaller things down. However over the course of about a week. I have been throwing up everything I eat or drink. And it's not with nausea... i feel completely fine before and after. I was thinking yah my bodies so used to just getting rid of it, that it does... however I am severely dehydrated from it. And I've lost more weight then i need to. My doctor has me on prilosec 40 mg a day, and i've been on that for quite awhile. I mentioned it to my general practicioner, who put me Phenagran, however it doesn't help at all and I am dying here... I wouldn't normally complain, however I go through this cycle. Where I'm so thirsty, so I'll drink only to throw myself over the toilet 5 seconds later and then I'll get so thirsty again. Even at this moment I'm on my 10th round of drink, throw up, drink, throw up. And its horrible. I can't stop. Does anyone know what causes this? And how on earth I can stop it. Because if i don't stop it now, I'm going to end up getting stuck with an IV and i hate those things...
