HOW WILL I KNOW?????

I wanted to thank everyone for their help. I am still not eating, but yesterday I managed to take a bite of chicken and keep it down, but I am still extemely nauseated. I went to see the dr. last week. He told me this is normal. It is just so frustrating, when I was released from the hospital the first time I felt fine, but when I had to be re-admitted 4 days later, I have felt crummy ever since. I have been told to make sure that I do not get dehydrated. I am nowhere close to drinking 64 oz. , maybe a glass in half. How will I know if I am dehydrated and if I went to the ER will I only stay for a few hours? I started back to work two weeks ago because I don't have much sick/vacation time left. No matter how yucky I feel, I know this was the best decision I have ever made!!!!!

Just curious as to who your surgeon is. I haven't had surgery yet, and am wondering if I picked the right place, because mine was listed on here, but now he isn't. I don't know if something happened or not. Thanks
