I never really get to sleep until about 5 anymore I wouldnt start smoking weed before bed. When you dont have any, it can be even harder to get to sleep, and its never really good using it as a neccessaty. I always have the TV when im getting to sleep, last night for instance I was entertained by JK for a while then went to sleep half way through. When I try to get to sleep I never can, then I get angry and start moving around. But when im not bothered about it, I just think "I'll just rest my eyes for a second", thats when I get to sleep easily... Have you tried sleeping pills?
