Exhausted

Ap

Who felt exhausted right before they went into labor? I was in L&D all day yesterday with contractions but they only got me to 3cm and I got sent home with no futher change. They gave me a shot of morphine which got me loopy and tired but now all today i've been sleeping on and off, I swear I could sleep all day if I didn't have my kids with me.

Is this because the morphine or because labor is actually near this time?
