I'm needing to know more than the net. tells me about how , if at all ,the body's blood sugar is affected or how blood sugar affects bipolar disorder . I did not sleep well last night , only about three hours. I read on Mayo clinic site (I think ) that lack of sleep can create a higher level of blood sugar that can I think induce mania type reaction. I am confused as I got up feeling awake ( from 3:00 am ) all morning until I ate some cereal with about 26 grams sugar at about 11:00 am. I began feeling sick ,anxious and just not well at all about an hour later. I will be asking my doc. about this ,but until I see him , Can any one give me some idea what is going on . It is 1:30 pm now and I feel a bit better but still not great , I'm jumpy nervous . Thank you .
