Hi, after coming back from las vegas, i have been throwing up about 10 times/day. Initially they thought it was food poisoning and then water poisoning from either vegas or locally. I have been to the local clinic for an IV and sent home for three days in a row - - then I was admitted to the local hospital for dehydration and they released me - - i was feeling about 10% better. Still, after 3 weeks, I have the same syptoms of constant nausea and the doctors/hospitals don't have an answer to what is wrong. i was told today to go back into the hospital. I find it hard to believe that nbody has an answer. I have had blood samples and a colonostopy performed but am waiting on the results. My husband works full time and we have a 3 & 4 year old son which means it is very hectic as well as we have sold our house and buying a new home on 8-18-03. If anyone has any info or has experienced something similar, please let me know!! Thanks
