My husbands blood sugar readings have been between 230 & 250 for quite some time now. No matter what he does it rarely goes below the 230 range. I had not thought of this until recently but am wondering can high continuos sugar levels like that have a impact on his personality. He has been horrible to live with. He has gotten extremly critical, demanding and downright angry all the time. He really doesn't watch what he eats, he eats at least 2-3 packages of pork rinds a week, drinks only diet pops and koolades, and refuses to drink water at all. I think he does this to spite me. We have been married 37 years, for the past several years I cannot do anything right, not dishes, laundry, housework, weeding my garden, nothing without him yelling very loudly at me to where even neighbors can hear, he has even yelled at me in the car driving down the road and people turn to look as they pass or as they walk down the road and in parking lots. He is very careful to not display this kind of action however in public, such as stores, church, or anywhere in buildings outside of our home. Our daughters have all witnessed this action and do not know what to do, they have talked with him but to no avail Is this normal? I have learned to ignore what he yells about and sometimes have gotten to laugh it off. In the past couple months he has made statements many times during the day that he wished he had never been born. I need advice. Anyone? Thanks.
