Help... I think I'm addicted to colonics!

I discovered colonics at 17 and have been doing them -on and off- for over 8 years. Instead of becoming more regular I've reached a point where I almost don't go to the bathroom on my own. My rutine is having one colonic a week. People please... how much is too much? How can I fix this problem and teach my colon to go without external help? The feeling of being constipated drives me insane. THANK YOU!
