Restless legs syndrome

I’m 30 weeks pregnant and I seriously losing my mind. I’ve been having horrible RLS the past 3-4 weeks. This has made my nights a complete nightmare along with getting up to pee every so often.

I have been taking half a pill of the unisom I was taking for nausea during my first trimester and it has helped me sleep, but I’ve noticed I wake up super groggy and sleepy. I’m also not sure if it’s safe to take this every night. I assumed it is since I was taking it a lot at first.

Has anyone been having this issue? And if so is there anything you recommend to make it go away?
