Still plugged from unsuccessful flush 3 days ago

As I wrote on a previous post (page 9) the last flush produced nothing exept that it put my plumbing out of service, big time. Constipation is generally not my thing, if anything, I can lean towards the opposite, but have been very regular lately, until now.
Yesterday evening I drank two tall glasses of prune juice, also a glass of water with a tablespoonful of Epsom Salts last night, also took an enema, which produced a minimal amount of BM. Woke up several times to a lot of noise in my intestines. Was sure there would be an explosion of diarrhea any moment. Wrong. Again NO BM in the morning. Finally some small thinly formed BM's in the afternoon . Now it's 6 P.M. Wednesday. I have been eating normally since Mon. night, where is it all, and why?
I am afraid to do another flush. Can Epsom Salts plug one up once the body is used to it?
