I MISS SLEEP & he’s not here yet

So I’m the person who has to pee the second she wakes up, once I do there is no going back to sleep. That was fine until we got pregnant and I started waking up with a throbbing bladder at 2a.m. if I manage to fall asleep that’s great, but when I wake up again at 4....I’m just awake. Any tips for sleep???
