So your poor husband had a bit of a moan about the realities of looking after someone who is incontinent. My goodness, how utterly terrible of him! Honestly, you have to feel very sorry for him if he sometimes finds this unappealing. As someone who has had to do this for her step grandmother, her grandfather and her mother, I have huge sympathy for your husband.
As for the trying to get away and resisting attempts to help, it sounds so much like a hypoglaecemic attack. This can also happen to non-diabetics: Hypoglycemia is often related to diabetes treatment. But other drugs and a variety of conditions — many rare — can cause low blood sugar in people who don't have diabetes.
As hypoglycemia worsens, signs and symptoms can include:
Confusion, unusual behavior or both, such as the inability to complete routine tasks
Loss of coordination
Slurred speech
Blurry vision or tunnel vision
Nightmares, if asleep
These attacks are often confused for being drunk. Alcohol can occasionally cause this because the blood sugar shoots up quickly but then drops like a stone as the alcohol leaves the system. The NHS website says this about causes:
What causes a low blood sugar level
In people with diabetes, the main causes of a low blood sugar level are:
the effects of medicine – especially taking too much insulin, medicines called sulfonylureas (such as glibenclamide and gliclazide), medicines called glinides (such as repaglinide and nateglinide), or some antiviral medicines to treat hepatitis C
skipping or delaying a meal
not eating enough carbohydrate foods in your last meal, such as bread, cereals, pasta, potatoes and fruit
exercise, especially if it's intense or unplanned
drinking alcohol
Sometimes there's no obvious reason why a low blood sugar level happens.
If this was the case, your husband couldn't help his behaviour and would have had no warning that he couldn't drink alcohol. Berating him is a bit like giving him a hard time because he has epilepsy or appendicitis!
