I wanted to know the effect of dipenhydramine on type 1 diabetes. I am a 30 year old woman, diagnosed with type 1 diabetes in Feb 2011 (but suffering with it since March 2009). I have had GI symptoms of unknown origin for the past four days. My temperature remains at 97.9 or below, but I have spells of nausea, abdominal discomfort, and what seem to be hot flashes.. My blood pressure, and pulse are normal. My blood sugars are relatively normal. But I began working night shift as a nurse two weeks ago and take sleeping pills to help me rest during the day. I have also been juicing almost every morning for the past month, and am concerned about the possiblity of a bezoar. I have never been diagnosed with gastroparesis. I am usually constipated, and must use teas, home remedies to produce bowel movements.
