Good old Bremby, dogs just know don't they. My old Boxer dog Cassie would jump into my lap in the armchair every night and when I got the Snip (over 20 years ago) I was crapping it for a few days as she would normally just leap up in a split second. For a week after she just came in and sat at my feet until the day I beckoned her up onto my lap again
If your back condition is muscular Tone, alcohol may help as its a muscle relaxant but if its skeletal or nerve related, it won't help and as you say, you don't really want to wake up and go to work with a bad back and a thumping headache. Having suffered a prolapsed disc myself - I truly feel for you matey.
