Oxy-Powder for chronic constipation?

Hello I've had suffered chronic constipation for the past 10 plus years or so and have tried everything from probiotics, prebiotics (inulin), metamucil, magnesium citrate, castor oil, inositol, mastic gum, manuka honey, berberine, etc...

None really work except castor oil, although its not recommended for daily use. So I stumbled upon Oxypowder from this website. The reason I did not use it before was because I thought it was simply over priced magnesium oxide. Although after researching more from this website I find that it is 'ozonated' magnesium oxide.

I've tried just one the other day and its really aggressive, so much so that I don't think I can handle it and will have to slowly titrate up with it. I read that it increases the oxygen in the entire body as well due to the ozone, so maybe its just a strong detox reaction. Any other experiences with this?
