Hey Amelia, I was the same. Didn’t sleep one bit the first night, then rang my PC about it the next day and she told me you don’t actually need to sit upright, you just need to make sure you stay on your back. A few girls on here seem to think otherwise and I realised that’s where I got the upright sleeping thing from in the first place! Perhaps one of the surgeons recommends it, but yes, you’re fine to sleep on your back straight away xx
