Hi Greenmouth

My Oh and I had this problems for years, (we got married in 1982) I used to wake up in the night with him sitting up in bed reading etc..
Then earlier this year we decided to try seperate beds and bedrooms, although I was upset at first it has been a blessing because I sleep right through the night now and I feel restful.
I'm not sure what the answer is for you, but have you tried Lavender under his pillow, or apparently you can buy a lavender pillow.
