marijuana for sleep

So i suffer from anxiety, it affects not only me but my family. Ive tried medication but it make me foggy,bad headaches,heart palpitations etc. When I have a good nights sleep I have way less anxiety. Problem is I can never get to sleep before 1am then wake up at 7 ish with the kids. however there been like two times Ive smoked pot and been to sleep at a decent time and wake up feeling good and happy. It almost legal here. October 17. I cant continue like this and medication just doesnt seem to be for me. I want to start working out cause I know that helps too but for now I just need more sleep at night.
