Early 1st trimester insomnia

Elizabeth
So early... Just got my BFP and I haven't slept the last three nights. Combination of excitement and anxiety, I think. 
​How do you get to sleep and stay asleep?
​I usually use essential oils, and if I really need to Tylenol PM, but I need to consult my doctor about those apparently. 
​Help! I'm barely pregnant! I thought I would at least get a few more months!
