I’ve been trying to sleep on my back for a while now and ive had success like i managed to fall asleep and i didn’t wake up on my side. Im doing this because i heard it helps with symmetry and makes the face less puffy in the morning. It’s been kinda painful tho to force myself to fall asleep when im not in a position im comfortable in and when i wake up i feel pain for some reason and want to go back to side sleeping even tho i slept on my back for the whole night. Are there any side effects of sleeping on your back like jaw drooping, mouth breathing or anything like that (i havent noticed any of those but just to make sure) and should i go back to side sleeping if i feel pain when i wake up?
