My concern was that they told me not to lay down, but to sleep sitting up, and not to just prop myself up because the pressure on my band would be uncomfortable. However, since I posted this I talked to my nurse, and she told me to sleep in whatever way I was comfortable, even on my side. I know it's silly, but after I spent months to get approved, working through the insurance restrictions and trying to do exactly what I was told, I realized that maybe I should pay more attention to questions I should ask.
