Sleep Issues

I'm still having sleep issues.  Very uncomfortable sleep issues.  It's driving me crazy.  I keep waking up at 3am, 6am and 9am.  At 3am it'll usually take me an hour to get back to sleep.  At 6am it'll take me two hours to get back to sleep.  Then I'll wake up at 9am starving and feeling nauseous.  I started feeling really nauseous when I'm hungry so I have to eat something or I just won't feel well.  I usually have a packet of oatmeal.  Then I can go back to sleep until 11 or 12.  My sleep pattern is all off.  I guess I really am preparing to be woken up every three hours.  I periodically get Charley Horses in my legs.  A couple days ago I had it in both legs.  Joe will usually massage my back to help me with the pain (he's preparing for my labor too) but he's been sleeping in the office room all week since he's sick.  He quarantined himself from me hoping it'll keep me from catching his cold.  Poor guy, he’s been feeling pretty miserable too.  I've gotten hip pains from sleeping on my side and last night I had joint pains in my knees that hurt and were really uncomfortable.  All that makes it harder to sleep.  I'm so so tired.
