If you had pregnancy insomnia does it get better after birth

I have such raging insomnia that I have never experienced before, this is my second baby and I never had this with my first, I literally can stay up the entire night. My body will be so tired and I start to feel nauseous I’m so tired but my mind just won’t shut off. I take unisom nightly as directed by my OB , but even with that it still takes a few hours to fall asleep and I wake up in the middle of the night to pee and then stay awake.

It’s actually so awful. I remember sleep deprivation with my first as a newborn because she never slept , yet somehow this is worse than that. Someone please tell me they were able to fall asleep once their baby was born because I’m gonna lose my mind 😭
