I get bloating from diet coke and caffeine free coke. Caffine free is the worst, that has caused me problem for several years before anything else really started bothering me. The artificial sugars have given me headaches for years but, the gluten intolerance just started/recognized . I have been trying to get gluten free. It is not easy. I live in the US. Your not alone with having Carmel coloring issues. Hugs. I guess from what I've learned from other posts here it gets better and easier. I am amazed at benedryl. It helps hugely. When I make a mistake. My skin looks like really bad windburn on top of stomach ailments. And bendryl seems to help my insides and skin not react so horibly.
