Hi, I feel for you, I suffered for years. I tried all the concoctions from the doctor, with small benefits. In the end I got so fed up of it, I changed my diet completely. Clean eating, changed my life. Then I slowly introduced processed foods and found that certain food triggered me off. I have cut out the culprits and try to eat clean when life allows me.
I did find hot water and fresh lemon helped, although lemon is an acidic fruit, when consumed it acts as an alkaline.
