Hey, I've been having trouble sleeping. Especially when my husband goes on night shifts, I can't fall asleep at all, sometimes I even wake up in the middle of the night and can't fall back asleep. Sometimes I get a few hours of sleep but then I wake up again and can't fall back asleep. Has anyone experienced this or do you have any suggestions for what helps? What works for you? I can't keep doing this without getting enough rest.
