So I decided to do an enema an hour thing as well, and will be taking an enema every hour, progressively increasing volume by half a quart every time, starting with 1/2 quart and hopefully finishing at at least 4.5 (I never gotten that high) or even 6 quarts! But probably not. As I am typing this, the nozzle is in me, 1/2 quart of black nasty M&M solution is in the bag, and all I am waiting for is for the clock to turn 12. Let the enema games begin!
