I didn't know I could be this exhausted.

Is anyone else sooooooo tired? I've been sleeping about 10 hours a night. And by mid morning I'm drained!!! I used to workout 7 days a week and now I barely have the energy to go to the grocery store. Honestly I'm surprised I haven't gained a million pounds get with the total inactivity and the nausea- all I've been able to stand is carbs. Pasta, pizza, carbs. Does anyone else feel such utter exhaustion?!?
