Feo, I definitely have been considering them. I haven't done one for a while. The last one I did made me feel very anxious with lots of nausea. I'm now thinking that perhaps I did it wrong. I may have set the bag too high and allowed it to circulate throughout my entire colon instead of remaining in the sigmoid.
I plan on doing one on my next day off of work, just in case there's a reaction.
One concern I had though is that doing too many enemas may cause the peristalsis to get sluggish and lead to constipation. Was this ever a problem for anyone?
