Trouble sleeping

Is anyone else having trouble falling asleep? I’m usually pretty good about falling asleep by 11PM since I’m up at 6:30 for work, but the last week or two I’ve been tossing and turning and feel like I could jump out of my skin until at least 3AM every night. Any solutions you lovely ladies have come across? I’m not sure how much longer I can live on 3 hours sleep a night.
