I had takedown 5/31 and I felt sick to my stomach. They had me on zofran as well. It will get better. My bowels had been sleeping for over a year. I'm at home now but they wanted to re-admit me into the hospital because I just had an x-ray done and my intestines are twice the size they should be and I'm extremely bloated so something wrong is going on. I have to get a catscan tomorrow. I'm on 2 antibiotics. I'm going to the bathroom about 6 times a day. That seems to be going fine.
I'm sorry to hear you are throwing up. I dry heaved a lot in the hospital and it's the worst! Give it some time and I hope things will get better for you.
