That's NOT the way to fully empty the system!!
Here's the problem: The small intestine discharghes some of it's contents into the large intestine about every 20 minutes, give or take.
Likewise the stomach discharges part of it's contents into the small intestine at about the same rate. althouth NOT necessarily in sync. In fact, USUALLY not!!
As a result, enemas, by themselves can ONLY clear the large intestine, no matter what is in them.
I generally clear my large intestine with an Epsom Salt and soapsuds mixture, together in the same enema, retained 15 minutes for the first round. I HAVE used 2 Fleet Enemas in place of the Epsom salt. I then repeat the same without the saline for any subsequent rounds, until a clear return is achieved. Typically 3-4 rounds. Sometimes more!
When I'm really doing a total cleanout, I actually take a personal day from work, and clear the schedule first.
I really start the day before. At lunch, I eat WHAT I normally would, but only half as much. No more solid food for the rest of the day after that. I knock off any alcohol after 4 PM, and any caffeine after 6 pm. I load up on water about bedtime,
Upon waking the next morning, I take 6 bisacodyl tablets(Generic Dulcolax) It needs to be at least 90 minutes, and no more than 3 hours before I start the enema.
Now that I'm married, I have a husband to take care of the twins, dog, etc.
I then take the above enemas to clear the large intestine. Although bisacodyl is really only active on the large intestine it speeds the whole process up enough that, with an empty stomach, and by the time it kicks in(and KICK is exactly what that stuff does) it is essentially moving the content of the small intestine, so that by mid afternoon, the whole system is clear.
I used to do this 3-4 times a year, but now that I am a Mom, a dog owner, an home owner, and an experienced worker at a full time job, if I can do it twice in a year, that's what I can reasonably expect.
Another method is similar, but instead of taking the bisacodyl BEFORE the series of enemas, you can do a magnesium citrate AFTER. but be careful! One issue with Epsom Salt is it's rather narrow therapeutic window that is, the difference between a thorough purge and a dangerous overdose is not very wide. The problem can occur also, when you do magnesium citrate, because that's really quite a lot of magnesium.
