It may not.be ideal but I took full advantage of the one glass of wine a day rule. Id soak in the tub and sip a little wine it put me righ to sleep you could also ask your doctor about sleeping.meds
I have had a hard time sleeping my entire life and its been steadily worse being pregnant. Sometimes I take a shower and then try to sleep which helps. Having a noise machine or the tv on really low helps me not think so much I cant sleep. Always having something cold to drink by the bed, a humidifier, and a fan also help alot!
I'm in your same situation! I'm 34+3 and haven't gotten a good night sleep in over a months. Good luck it's a pain.
