I remember that same thing happening to me. But, for me it started when I stopped nursing before putting baby to bed. I dont know if it was the change in routine or missing the relaxation and hormones or whatever thats released with nursing- that made me no longer be able to get to sleep. It probably was anxiety. I think I had trouble with that and never knew it. I would try something from the health store before from the DR. Prescriptions are way too strong and has a lot of side effects. Look up Relora & see if its something you'd wanna try. Good luck.
