I Am Having A Colon Hydrotherapy Tomorrow, I Suffer From

I am having a colon hydrotherapy tomorrow, I suffer from IBS-D, in the last 2 years I have changed my diet, and able to control it somewhat, however I suffer from bad breath, gas, and bloating lately, so imagine how miserable I am, my insurance doesn't begin till November, so hopefully a visit to a GI doctor will be a start, I had a colonoscopy last year (all normal) just need some direction advice or suggested remedies on my problem
