After many hours pass by since last food intake, acid production should be dropping down. IOW if you go to bed at 11pm, by 3am there should be lot less acid in the stomach, and switching to right side after 3am should not cause serious acid re-flux.

Ground beef can be a ticking acid bomb with me. Don't have enough information to understand what "kind", or under what circumstances, but the acid production will wake me up.

I don't think it matters what side I'm sleeping on, either.
