Have you tried the lower bowel balance caps from MH? I used to not go everyday either...like every couple days and it wasn't anything substantial. I've been using the LBB for about 10 months now and I can't tell you how much that one formula changed my life. I started going everyday and I felt SO much better!
Enemas are not meant to be used daily. You need to get your colon to work properly on its own and the LBB can help greatly with that.
Whats your diet like? Once I got off all sugars and bread and just all junk food in general and switched to a mainly fruit and veggie diet, that made a tremendous difference for me as well.
