The method of getting a colonic she chose is different than the one I tried. My wife paid to have me get one because she gets them all the time. Only there wasn't a little tube that you self insert just an inch. A registered nurse / colon hydrotherapist trained in the process used a machine with a 1 inch diameter tube with a tapered end....and uhum... after applying lubricant she put that up my bum about 4 inches. Not exactly comfortable, but not really painful either. Just felt weird, and embarrassing. The machine is used to fill your bowels with water until you feel the urge to go, so she just turns a knob and everything goes neatly down a clear hose and into the septic system. There's even a lighted tube to see what's coming out. To me it felt like 45 minutes of on and off diarrhea cramps. You sit on the loo for a few minutes after the session is over.....then get dressed and leave.....and try to forget you just had that happen to you LOL. All in all it's not that bad. I've been told you need to have it done three times in a row to notice any benefit. Just not for me.
