Improve my posture

I was doing so well with sitting up straight and keeping my shoulders back when I was standing up. I thought the whole slouching pose was gone…. But my in-laws were in town for the past week which means I have had little sleep because I was up late visiting with them. I can’t believe how sleep deprived I am… which means I am slouched over when I sit because I hardly have the energy to fight it. My goal for next week is to get to bed and start getting back in to a normal sleeping routine… which in turn helps 90% with my posture.
