pj, overall it sounds to me like you had a good session. It is not that unusual after a colonic to feel like you have eliminated everything, only to find after leaving, and at the most inconvenient time possible that you all of a sudden have to go very urgently.
Actually, I can personally relate to it. When I was a senior in high school I went to Orlando with 3 of my friends for Spring Break and stayed with my aunt, my mom's youngest sister. After 3 days I was exhausted and totally constipated, and while my classmates went to Disneyworld for the day my aunt drove me an hour away to Cocoa to her therapist for a colonic.
I had had colonics before and everything went well, and when we left I thought I had gotten everthing remaining out on the toilet. But about 20 minutes into the drive back home, in the middle of nowhere with only sawgrass and swamp on both sides I got these intense cramps and incredible pain and couldn't hold it any longer. My aunt pulled to the side of the road and I just got out and squatted and released. There was no other choice. It only took a few seconds and although at the time it was the least of my worries, my aunt said that only a couple of cars went by on the other side of the divided highway.
My stomache was still unsettled when we got to her place and I readily consented when she said she wanted to give me a clear water enema to rinse out any remaining waste still inside. What came out was very dark concentrated liquid and I felt nauseous.
Afterwards I fell sound asleep for several hours until I heard the noise when my friends got back. By that time I felt terrific and was ready to go out for the night, but they were all exhausted after a long day in the hot sun. So I can personally relate to what it's like when everything doesn't come out when it's supposed to.
I like what you are telling us about your therapist. It sounds like you found a good one.
You are doing the right things and I'm confident that they will yield benefits not just now, but over the long term.
All the best, Val
