Alternative for enema with salt water flush

I have done the Moritz liver cleanse and each time I had severe constipation afterwards. I did do Bowel Cleanse with a simple 2 liter home kit. After 5 days still didn't have any bowel movements. It was scary, never had any issues before the first LF, but thanks to the (sea) salt water cleanse I found it is all right now!

I used 2 tablespoons on 1 liter of water in the morning after not eating the evening before. I know they say 2 theespoons instead, but that didn't work for me. Also I didn't want to drink the water too fast because I was affraid my gut wasn't going to hold it with this severe blockage (probably a lot of dried up gall). I don't know where I would have been without this SWF.

I suspect it was the epson salt drink in the next morning, because I had too much left that morning and drank it all. That made my constipation way way worse than the former times.

Now I am considering this SWF (Salt-Water-Flush) instead of the enema at least for the pre flush for myself. And for my parents who are at a certain age (one of them has alzheimer) the enema is not a thing they can handle at home. What do you think of the SWF (Salt-Water-Flush) (in the liver flush), it was so effective for me, anyone have (also) experience with this?
