Please talk to me about impatience/anger/rage in type 2 diabetes. Is it very common? I think my boyfriend might be experiencing this. He gets very demanding and argumentative and a bit haughty and relentless at times. I'm not sure if it is linked to diabetes or not; my sister's husband is also diabetic and she is the one who told me about diabetic rage. Says her husband sometimes gets unreasonable, relentlessly argumentative and even mean..and then he denies it (forgets?).
