Insomnia!!!

Nicole • Mom of boys!!! Anthony born July 2017 & Joey arriving in February 2018.
I am officially into my 12th week and dealing with some pretty wicked insomnia. I am usually a good sleeper lol but these past few days I am having the hardest time getting a deep sleep. I don't want to take any melatonin because everything It tells me not to. I have an appointment with my OB on the 18th so I will ask her for any solutions but in the mean time does anyone have any tricks?
