I can sleep all day

Literally! I mean I work full time but I sometimes take an extra hour for lunch to go in my car and sleep. On Saturday I slept from 6pm-8 am and then took a nap at noon on Sunday. I feel like a bum and can't commit to plans bc I'm tired. My daughter has been staying with her dad bc of this. I'm not a coffee drinker but I need something.... so how are y'all pulling through this LOL. Oh and the nausea never ceases either!
