I just had surgery to remove my terminal illeum, right colon etc. I did the osmo-prep tablets. It is a lot of tablets to swallow but you can wash them down with any liquid you choose. I found water to be the easiest but that's just me. My surgeon also gave me compazine tablets for nausea which helped a lot. Like you I was already pretty sick and wasn't eating or drinking much at all for a couple of weeks before surgery. I was so dehydrated by the day of surgery that when they asked for a urine sample, it looked like I poured tea into the little cup. That kind of freaked me out but after some IV fluids it returned to normal. I also had to take Neomycin and Flagyl three different times on the day before surgery to make sure my bowel was more bacteria free. I was really worried about taking antibiotics on an empty stomach so the compazine really helped, keeping me from feeling like I was going to vomit. You should also ask your anesthesiologist about a Scopalamine patch before they take you to the OR. It is for nausea and works for 72hours before you have to remove it. That was my biggest request to the anesthesiologist "please don't let me wake up sick and vomiting". I hope your surgery goes well. Keep us updated, good luck!
