Report This Post (To report rule violations to admin) Could celiac really be making me feel this bad? in Celiac Disease Pre-Diagnosis, Testing & Symptoms Posted April 3, 2016 Hi again. Kam - it seems that six weeks is the recommended length of a gluten trial in the UK if you need to reintroduce it and I am fairly sure my own doctor said at least two slices of normal toast every day would be adequate - but you might want to check that. https://www.coeliac.org.uk/coeliac-disease/getting-diagnosed/ I took it upon myself to eat everything I could that I knew would be forbidden once I was gluten free so ate Weetabix, Twix Bars, Penguins.... It brought back a tight headache across the temples that I hadn't had since I was at school. I can almost feel that headache again just thinking about that gluten trial! I sometimes have the sweet taste but it has been down to new toothpaste or artificial sweeteners in drink. I get very shaky sometimes if I am not eating regular meals.. If you are concerned the blood test for diabetes is very easy. Have you had a test before? Joan b - I was put onto citalopram when I was undiagnosed. It was a very small dose so I am still not sure whether it helped or not although I think it probably took the edge off things. I felt worse for a few days when I first took it which apparently is a common side-effect. It is worth remembering this - things should get better soon. In my own case I found it was definitely worth looking at other life-style factors such as getting enough exercise, sunshine, omega 3 etc in the meantime.
