Normally. if I do my fasting the right way I need no more than 4-5 hours to get to a complete cleanout. And then a couple more hours lying around not doing too much just to be sure.
If I haven't gotten a clear return after about 4 hours, the last thing I feel like doing is taking another enema, but I DO finish the job.
There was just once. The summer between my freshman and sophomore years of college when I was spending the summer at the house I grew up in with my Dad Turned out to be my last summer spent at home.
I did my scheduled system cleanout, and for whatever reason, I just kept expelling brown! 4 rounds, 5 rounds, 6 rounds, all in knee chest with satisfactory retention times. Finally got there, after 7, that's right 7 enemas! and was able to get to the final round, a thick, soapy 4-qt enema, given in Simms position with a barium-type nozzle! That still came out yellow. Finished off with a bottle of Magnesium Citrate to get the last of the soapsuds and anything left in the small bowel out.
That was the only time an enema session has taken more than 6-1/2 hours. That took nearly 10!!
Hope I never have to go through that again!! I was light headed, with vertigo and could barely move my the time it was over!
