Thanks for the concern everyone but Its clearly the sugar fluctuations. I've documented this and I know my body extremely well living with this 36 years. I truly wish this wasn't the case but it is. What I don't know is if there is another underlying problem that when the sugars fluctuate it magnifies it? Sometimes if I am real low and just eat a little initially I may feel even worse thinking my sugar is high only to check and get a reading of 68. Then if I am running even a little high and eat even a piece of sugar free gum I feel a slight spike and become even more irritable. Sounds bizarre but that's my reality. When I was younger and my sugar went low I got the typical shakes, sweats and numb lips but no mental distress that I could remember. When my sugars went high I basically pissed and drank like a fiend and my vision got a little blurry but never really remember being wicked irritable from it like I am these days and for the longest time now. The symptoms now are far worse and I am in relatively much better control being MDI and carb counting. I've been at whits end for years living like this.
