Like "Hello, This post is just screaming me!!! Before I was first diagnosed my hubby would actually cringe before I ate something because he knew within an hour or so I'd be a "screaming banchee" (his words not mine, I of course think I'm an angel). After I was diagnosed we soon realized that this behavior was due to me being so "high" after I ate. Now I am starting to notice me nose getting bent out of joint more when I get low. So basically to answer your question, yes I strongly believe that anger can be caused due to diabetes. Although there are some people out there that are just born sourpusses. Good Luck Blessed Be Vicki"
