Waking up 3-5 times a night..

I work in a hospital and I’m always on my feet. I wake up at 5am for work and don’t get home until 8 and usually go to bed at 9. You’d think after a long day I’d just pass out but it takes me an hour or more to fall asleep. Once I’m asleep I wake up 3-5 times a night to pee. I’m always exhausted. I tried taking sleeping pills and they don’t help. I’m going to see a doctor once I can get an appointment but that may take a couple weeks. Until then I have no idea what to do. Last night I came home after assisting on a surgery and my whole body was shaking but I still couldn’t fall asleep. Is there any strong sleeping pills anyone recommends?
