Try a shower with lavendar oil after it. Don't take in any stimulants the second part of the day. Drink something soothing, and read something that will put you to sleep. You could do the shower and lav. then lay down on your bed and do muscle tighting excersizes, do you know how to do these? Get plenty of liquids a day.
I'm going to guess that your a girl with your post name, and I suggest taking two non-carbonate calcium tabs or caplets, 1/2 hour to an hour before bed time, if you can find the kind with the magnesium in it, that's even better. They help each other. Also take a vit-c with bio in it. Or you'll need to take it with food with vit-c in it otherwise, to get the total mg of c your taking. Ester C has bio in it. This is what I told my mom to try, she swears by it.drs
