Not only you wake up hard, me too. Ica't remember for sure the position when I wake up. It can be different.
damn, COL has a goat harem! my all time fav cartoon: http://vids.myspace.com/index.cfm?fuseaction=vids.individual&videoid=2684477
I normally wake up in the middle of the tennis court, on the trampoline or on the grass. I do actually have a bed, I just don't choose to use it for sleeping!
I used to always wake up on my left side - but now it seems that I wake up on my back and in pain... sure wish I could keep myself from doing that!
