OMG, I thought I was the only person in the world who gets horrific headaches if I don't eat on time. Some of it may really be issues associated with having diabetes, but my hands get shaky, I turn into an absolute witch--snappy, irritable, light-headed, and of course the headaches--and that's even if my glucose reading is normal or even high. That's what scaring me the most, is the pre-op diet. I'm going to grit my teeth and do it, but I've already warned my husband that I'm going to be nearly unbearable to be around. I hate headaches! :sad0:
