I am having some DNA testing done too, hope it helps to narrow down what meds I need to be on rather than playing darts in the dark, hoping to hit the 'target' you know? You will sleep a lot better once you get a good mattress, I don't have a sleep number one. But I have a sealy and love it. I too can't sleep on my back, it's just too painful. I sleep on my sides or I can't sleep well.
