Does anyone experience an episode wherein they have a sugar rush only to have it bottom out suddenly? This happens to me quite a lot. I wil have breakfast, usually some cereal with 2% milk and no added sugar. Along about an hou and a half later I will all of a sudden start feeling sick to my stomach, dizzy and like I want to die. All of my doctors have different comments on this. The psych doctors say a panic attack, I take xanax. The medical doctors say they don't know why. My blood tests are normal. Finally, because my husband is a diabetic, I have him check my sugar level with his machine. The readings have been as low as 43 when I experience this feeling. My internist says that I could have blood checked again, but I would have to experience this situation while there. Almost impossible, as I never know when it will happen. Anyone else experience this?
