If you have another bedroom that you can sleep in, that would be my recommendation. A Caregiver can't function well without proper sleep, and there's a point in the progression where that's the best way for you to sleep.
My husband’s doc said for him to take Melatonin 5 mg before bed. That has made his sleep activity much less difficult.
Please ask his doc about melatonin. It makes a huge difference for us.
I have done that but after 45 years of marriage, it is hard.
Both husband and myself take melatonin at night...husband has had insomnia always...also TV off 11pm...blue light from TV isn't good.
