I am the Queen of insomia darling! I say dab a drop of Lavender (yeah, like I'm sure you have some...lol) on your pillow, relaxing music and maybe sex?
If not I say Ambien or Lunesta (but addictive be careful)
At a certain point if you try to hard you'll get frustrated and there is no way you will drift off, just lay in bed and relax enventually you'll sleep! Good luck hun!
