I made sure I stuck to sleeping on my back Hun (despite the bad backache) for 6 weeks as I wanted to make sure I would get the best results……it is hard don’t get me wrong, up until surgery I’ve always slept on my side. I too was scared of displacing them and thought I’m spending a lot of money on them and going through a long recovery, I would be gutted if results were altered because I didn’t follow the best guidance of sleeping on my back……Xxx Stay strong, it will be worth it xx
