We cannot sleep together in anything less than a king-size bed - & Mrs HAL takes up 75% of that. I also suffer sleep apnea & can snore the roof off but have a CPAP machine now that takes the sting out of that.
By the way Crumpet, my wife tried that trick on me & I can sleep through that treatment - it freaked her too much when I would not wake up - probably an effect of sleep apnea.
Far, far better than separate beds!
