Sleeping on My Back

Yes, I have cancer, and yes, I had a huge surgery, and wouldn't you think that that would trump everything?  Well, of course, both of these things are foremost in my thoughts,  how I am thinking and then working hard to put on my very best attitude, but guess what?  Sleeping on my back is slowly driving me nuts.  It is such a little thing, but despite all of the health reasons to do so (and apparently there are many), I just simply cannot get comfortable on my back.  So as I go into my third straight week of having no other option, I am thinking of all sorts of things to do to ameliorate it.  Maybe I can prop a pillow so that I can tilt ever so slightly to the left or the right.  Maybe I should try some guided imagery to help me drop off to sleep without thinking about it.  But no matter what I try, I still left with that "turtle of my back" sensation of being trapped on my back each and every night.  I am amazed that in the midst of all the really serious things going on in my life that I can still be bothered by the very tiniest of things.  Just talented, I guess.
