Do what is right and comfortable for yourselves .... Some people bungee jump other won't.
I had a colonoscopy once without sedation over 20yrs ago, when first diagnosed with U C.
I didn't know what to expect and I was too ill to care but since, I always had sedation.
Same since colon removal, flexi Sig and sedation is always an option which I select.
On one occassion, on the day of the proceedure, the physician insisted I didn't need sedation, stating I will have to return in 3 months time for a sedated procedure, yet curiously when I agreed to that, the proceedure was performed with sedation there and then ?
I always request sedation due to my personal experiences and I still feel apprehensive just prior to the procedure.
