I had one done a about six weeks ago. It was a great experience. I saw a naturopath who had alot of experience. She only uses warm water and then puts in the good bacteria after it's over.I got completley cleaned out and felt great for a week or so...it didn't cure my constipation, though I'm not sure it's suppose to.It was nice being rid of the bloat and feeling so light again.It wasn't cheap, cost 60.00 (highway robbery), but if I had the money I would go more often.
