@alleycatkate I’d be surprised if waiting longer than 3 hours after eating would make much of a difference (unless it was a huge slice of cheesecake maybe!). Lower fat at that time of day will clear faster.
The magic for me seems to be actually achieving and sustaining a 30 degree angle between stomach/hips and head throughout the night. I couldn’t really get there with a wedge, but the mechanical bed and a zoned latex mattress did it. I have to manage not to slide down or off during the night, and keep my joints comfortable enough to actually sleep.
It’s a real juggling act! Good luck! Please let us know how it goes with the PPI's. I learn so much from everyone in this group!
