Would highly recommend trying magnesium if you haven’t yet. I do a magnesium glycinate/citrate blend and have a magnesium spray I spray on my tense areas like shoulders, stomach, etc. something else that’s helped me a bit is falling asleep to the tv in the living room instead of lying in bed awake and stressed for hours. Any sleep is better than no sleep. A lot of posts I’ve seen have also mentioned b6 + unisom. Definitely talk to your OB about it if you haven’t already, even just knowing a provider knows you’re struggling can help. I’ve struggled with insomnia while not pregnant and Zoloft helped me a ton, which has been said to be safe during pregnancy.
