Beadin as you know my tummy was awful too. I followed someone's advice here (sorry I forgot who said) and bought probiotics called Prio7 I think it was called and being taking them twice a day as well as drinking water with lemon, eating probiotic yoghurt and eating healthy stuff and my tummy is hooray much much much better!!!
Hope this maybe helps you. Mine was awful as well as nausea but sadly I am up 14 pounds!!!
