I had kind of an unusual experience just recently, a little over a week ago while I had been taking a series of enemas.
I was using my open top bag and had not been able to take a full bag during a number of fills. I had the bag at different heights while in different positions, after topping off the bag for each new fill.
I had done this 3 of 4 times when I then topped off the bag and hung it from the coat hook on the bathroom door, 5' 10" high, and then took the enema in the knees-elbows position...
All of the sudden I had a tremendous cramp! I was about in double agony.. I had managed to clamp the hose before pulling the nozzle out of my butt and then I literally crawled onto the toilet bent over in pain. Then, when I got seated I COULDN'T GO.
I was nauseous... I thought I was going to throw up. I grabbed a plastic bag and dry heaved into it a little... Mostly just a little phlegm. My dick had gone limp. I had decided too, that this would be the last enema today, maybe ever!
It was like I couldn't bear to put the pressure onto my gut to start the process... I just couldn't push. I started to relax though and pretty soon it starting coming out, a little at a time at first... I felt a huge wave of relief come over me. I was also perspiring, and light headed.
I was able to start pushing again. I felt so much better... So much so that I topped the bag off again and took another enema, this time with the bag hung from the door knob at a considerably lower height. I have done high enemas with that coat hook before, but I think that the one that had made me sick this time just went into me too quick, with too much pressure, under the conditions of what was going on in my intestines at that time. There was still a lot of stuff in me that hadn't moved with the previous enemas.
