A quick word on colonoscopies.............
I had my first one last spring. The only part I thought sucked was forcing down the 4 litres (maybe it was 8?) of the juice; 1/2 the night before and 1/2 the morning of.
Shitting through the eye of a needle was no big deal, and I was actually hoping to watch the whole thing on the monitor but 2 minutes after they put the IV in me it was "good night Irene". For the rest of that day I was careful not to blow any farts since I didn't want to shart my drawers.
Felt polished and ported though for a few days.
Fun fact: the stuff they put me out with was Fentanyl - only from a reputable source and administered by trained professionals.
