Hi 

I just wanted to update my original post.  I got my colonoscopy yesterday, which was one week from my doctor urgently referring me. I was really concerned about whether I'd managed the prep well enough for a good colonoscopy as I vomited both times while taking the moviprep. The first dose I managed to get down in an hour and was down to the last two mouthful and just could stop myself from vomiting. Thought I'd brought it all back up, but it started to work and I spent around three hours in the loo and was up once during the night. I took the morning dose slower over around two hours hoping it would be better but only managed three quarters of it before vomiting. Still went to the loo but less often.  

When I got to the clinic I was really nervous after reading some people's experiences but the nurse was lovely trying to put me at ease saying her daughter had it done the day before without sedation, so I felt a bit of a wimp when I said I was going to go for sedation but thought my times of  tough and brave (three kids without pain relief) was over.  

Going in for the procudure  and once again nurses were really nice, the lady doctor who did the procedure was too. It wasn't anywhere near as bad as I thought it would be, I did use gas and air during some of the more discomforting parts. But it was a lot less painful than I'd expected. 

My diagnosis was: no sign of cancer, several random biopsies taken to check for microscopic colitis, several Diverticula found, therefore Diverticulosis  

I also found out my Fit test was 16, which the doctor said was only slightly elevated but you can have a normal fit test and still have cancer, so anyone who has other  ongoing symptoms after a negative test should continue to speak to their GP. 

And they also said my prep was excellent!

So even though I'd vomited it had done  it's job. Though I must say I hadn't eaten much for about five days before my scan and stuck to the recommended diet and eating only very small portions. 

One final thought.  When I came out and was discussing the whole thing with the nurse she said they actually like patients to have sedation as it makes any extra procedures they might have to do far easier for them and the patient,  so anyone having this procedure shouldn't feel bad about asking for sedation.
