It's funny you say that. I can sleep on that side if I gingerly lever myself into a comfy position but my sleep was rubbish because When I moved off it or rolled onto it when asleep it woke me up.
I cant lie on my back either for the awful snoring. Been taking Co-Codamol and Foxy Naproxen which seems to do the trick. I have the naproxen left over from doing my knee in on the stairs. If they run out and there isn't a marked improvement I will be at the docs faster than you can blink
