I've had 2 colonoscopies over the years, one with sedation, one without (ouch). I was fine with both but without was very uncomfortable. When they did sedate me, it was with something like valium and I just had a feeling of being woozy. If I had to have it again I'd go that route.

On the subject of private prescription costs, isn't it amazing! I see my psychiatrist privately and she then writes to my GP who prescribes what I need. Suppose he's just glad the PCT is not having to pay for any of my psychiatric care or therapy.

Good luck with whatever you decide Nic.
