For several years now, depending on something eaten, I awaken during the night with bad dreams, whole body tingling, like a rush all over, my face is hot, will have to have bowel movement, thirsty, supper-dry mouth, ringing in ears, some heart palpations. I sit up, take deep breaths, drink water and it will subside in about a hour or two, but will sometimes repeat if I fall back to sleep. Benedryl does not help. Valaren seems to help some. I am gluten sensitive & sugar/fruit sensitive and the sugar seems to be a common component. I have been to ER about 4Xs where they always check my heart and it is ok. I am wondering if it is an enzyme response, or adrenal. I have tried to track my diet closely, and do better if I leave off all fruit/sugar. I basically do not mix food groups which helps. I am not diabetic, take no meds at all, am 68. Does anyone else have these symptoms?
