NO SLEEP!!

I am 10 weeks and for the last 3 weeks I have been sleeping from 9pm-1am and then I am up for the day. I have tried warm baths, essential oils, calming music, sleeping in another room....NOTHING is helping and I’m at my wits end. I work full time so I don’t get the luxury of a nap. I am trying so hard to avoid medicating but I don’t know how much more I can take. I am suffering, my work is suffering, my poor husband is suffering....please anyone with any suggestions are welcome to share!
