I know where you're at...when the wife passed I went from 8 hrs of sleep and a 500 lb bomb going off and not waking me up, to 3-4 hrs and a cat jumping on the bed waking me up. That was 4 1/2 years ago. Still have the short sleep cycle but getting better with the new lady here.
Home bench not set up yet but another month or so might fix that.
The Eduard masks will help
