@dfoster85 - I had oxygen from a nasal cannula after my C-section, too. I had placenta previa and it was supposed to be a scheduled C-section, but I didn't make it to my scheduled appointment and went into labor right at bedtime--and of course it was after a hard day.
I hated that nasal cannula, too. I was so glad when the night nurse took it out for me! But I had some saline drops in my purse, so I didn't have to wait.
