I no for me I had to reintroduce myself to a lot if things. Sometimes in the beginning your body may reject it, but them try it again a few weeks later. In the beginning I didn't eat much of nothing because everything gave me problems. I still can't have bread/toast because it won't stay down, but I can eat a tortilla wrap... I have lived off strawberries and watermelon especially for Breakfast or a late night eat. Ivey thirsty a lot so sometimes I can't wait the 30 minutes so I eat some watermelon to take away the thirsty ness or eat a cold orange... But can't drink orange juice lol... U just have to play around with things to see how it makes u feel.... Good luck
