I'm an incredibly rough sleeper! I go to sleep on my side, but constantly roll around and move during the night! I will always go too sleep on my side though! I als o have to have tigt fitting fitted sheets too, as regular sheets WILL get pulled off and end up on the floor! I also have to have fairly light weight covers, as I tend to wrap myself in them in the night, and wake up panicky thinking I am trapped if they are too heavy!
I also talk and occasionally sit up during my sleep, and move things that are in arms reach of the bed! My Ex used to get annoyed with me sometimes, but oh well! Not my fault!
