I'm almost 6 weeks pregnant and have been suffering horrible insomnia. Tonight is my third full night with no sleep. Every tiny sound keeps me awake or wakes me up right when I do fall asleep. I have had about 4 hours of sleep over the past 3 nights total. Does anyone have any recommendations? I get to work and am virtually useless because I'm a zombie. I'm a nurse at a busy healthcare facility so need to be on my toes. Any advice is appreciated!
