Troubles inducing sleep

Hi, I'm new here. I've been having regular lucid dreams (almost every night) for the past several months, and am getting fairly adept at it. But I am having troubles falling asleep to begin with. I figure that some people here are knowledgeable at certain techniques to induce sleep faster.

For me it usually takes between 2 to 3 hours to fall asleep from when I go to bed. I am diagnosed with insomnia and ADD so it is naturally difficult for me in the first place, because when I try to empty my mind, thoughts and sounds come rushing at me, until eventually I am able to lower my brainwaves to a stable theta state, where I begin to notice hypnagogic sounds and imagery in the forms of random sentences from voices not my own and seeing slight hallucinatory images, until eventually I fall into a sleep.

I am wondering if anyone here has any advice to offer on how to fall asleep in the first place. I've tried different techniques but can't seem to fall asleep any faster. I always look forward in expectation to my lucid dreams I have almost every night (or extremely vivid dreams) but am held back by my lack of ability to fall asleep.

Thanks for any help. I know this isn't lucid dream related, but would certainly help me in my ability to harness my ability to sleep and dream, thus giving me a better chance to control my dreaming.

Lay in bed and clear your mind. Don't think of too many things or it will keep you up. I used to be just like you with insomnia. Make sure you don't have anything that could distract you from falling asleep such as lights from other rooms or if you listen to music at night that could be a problem as well. Vitamins will help you fall asleep too. I think that you should maybe take a sleeping pill as well if you really can't fall asleep.
