Best sleep I ever had was the procedure. I had no polyps, dh did have few small ones with his. I took a drink you mix and drank through a straw, the second quart of it I threw up, I couldn't get anything down. I got through the night and was all clean.
The gas gave me cramps and I chewed the beano, it helped instantly.
Recoup quick!

Good luck on your test Bizi, start of the year focus on the parts of health you can.
