I am on day five after my ACDF and am feeling better than I thought I would at this stage. However, I fell very unsure about best sleeping positions, does anyone know if there is an 'optimal' sleeping position to promote good healing/ fusion and correct posture? This seems important as it is the most time I spent still and can't seem to find a 'comfortable' way to sleep. I tried upright at first but that feels quite damaging. Thanks
