I just had one at the beginning of this year. The preparation I took was something new on the market and it wasn't that bad at all. It was a powder in a pouch that you mix with water in a 8 oz. glass. For the life of me I cannot remember if it was 2 or 3 pouches, but anyway, stick close to the bathroom my dear and good luck.

The funny part that I found though is how many doctors do the procedure differently. I was put to sleep, my brother and a few friends I know were given a medication, (can't remember the name of it, senior moment) and was awake to watch the procedure being done.

Wishing you all the best David, with good results.
