They will give you anesthesia that will relax you and you will fall asleep. The procedure does not take long. When they wake you up you won't have any after affects, no pain, nothing. I have had it three times, already.
My daughter decided to do the pill cam recommended by her doctor which goes through the whole intestine into the large bowel so after she swallowed it she went shopping at the mall, went back and they took the data off it and then of course it comes out after your first bowel movement.
my sister just had one. She said that it felt like it was done in the blink of an eye. They give you some sedation. She felt like she blinked and it was done. Then she had an excuse to just laze around in her pjs for the rest of the day. They gave her pictures of her colon which was pretty cool :lol:
