I, too, have low blood sugar. Diagnosed as hypoglaucemic.(sp?) For awhile, dr's wouldn't test for it, saying it was just my bp dropping low. I bought a glucose monitor and tested myself for awhile. Finally went to a Endocrine dr. at Vanderbilt, and she confirmed it by doing blood work. Sometimes it gets really low, and I get weak. When it drops, my bp drops as well. I'll get a migraine, and super dizzy. I make sure I don't eat 'refined' sugar when I feel bad. I remember I used to wake up at odd times just CRAVING sugar. (worst thing you can do)I keep glucose tablets in my purse. (they are very cheap at the drugstore) I check my sugar probably once every couple of days, just to keep an eye on it. My doctor likes to keep track of it too. I keep a journal of IBS, Low BP, glucose levels and diet. (migraines and Rheumatoid arth. pain goes in there too) Fruit is good to snack on, peanut butter, those 'fruit juice ice pops' are good. Just something that's not a 'snickers' bar!! LOL!!That will send you in a huge low. Good luck and keep us posted!!
