@georgengondo First of all, you got this. You are stronger than you know.
For sleep, have you done any sleep aids, like benedrill, tylenol? If those dont work, can the hospital give you morphine so you can sleep? I suggest this because if you are like me, you will need sleep to fuel up for pushing.
I was also 41 weeks pregnant and was having contractions at home every 5 minutes for days, so I was going to the hospital daily to ask if I was dilated enough for admittance, and they kept saying no.
I'm not usually a person who likes taking drugs but when they gave me a small dose of morphine, I had a glorious 4 hours of sleep - the only hours of sleep I got in almost 60 hours. And I needed it because my pushing lasted 4 hours. I also didn't want an epidural but after 3 days of contractions, I just wanted to get my baby born. So they gave Pitocin, and immediately pain spiked so I begged for my epidural.
Try to sleep as much as you can, and snack on something tasty and easy to digest whenever you can manage. Congratulations, you are gonna be a mama soon!!
