Lemon Water works even better with distilled water. I have had great success with fresh lemon and distilled water:)
I have had IBS for over a year now and after trying everything that the doctors and friends and family told me to try, nothing worked. Until I finally tried Lemon water. I squeeze Half of a lemon into a 8oz glass of water and drink it over an hour hour or two. If you drink it too fast you are likely to get heart burn. But after two days of drinking this once a day I was regular and no longer felt bloated or constipated all the time. Good luck and I hope it works for you.
