Since the colon cleansing product you have been using were not effective, why don't you try other product?
I faced the same problem as you do all these while and last month my friend introduced me to use Digestive Enzyme, It helps breaking down the toxin and waste in our stomach and flush them out naturally through bowel movement.
I go to bathroom at least twice a day now, and my stomach is no longer bloated and no more uncomfortable. I would suggest you try it because it only took 1 day for me to take effect.
I would be more than happy to share the information with you if you're interested.
you can reply me via this thread an I will contact you.
