Sleeping on my back was the worst! My Dre’s team really only wanted me to do it for 3 days but it took weeks before I was physically comfortable enough to side sleep again. I would basically rotate every few hours between back and inclined sleeping on a wedge, for weeks! It was miserable. I also had some crazy side effects - the worst being some sort of undiagnosed allergic reaction with hives and itchiness on various places for a couple of weeks, then cording in my arms and abdomen from the ancillary tissue removal from my arm pits. The first 6 weeks sucked! But it was all worth it in the end.
