I asked my nurse at my post op appointment and she said ideally I need to sleep properly upright for a full 2weeks and if I’m struggling I can start to reduce the incline. But she would reccomend me trying to sleep like that for the full 6 weeks. But avoid my side compeltly. I think it’s to stop the implant moving, cause if your on your side the implant can move from the position it should be in. That’s why they don’t want you on your side at all in the first 6 weeks. It helps with swelling aswell. If you google it thought most surgeons say you can sleep on your back after 5 days, they all have different rules but all them reccomend no side sleeping x
