Astral projection, tips and tricks Options

Ive been trying to astral project for about 4 months now with no success! I let my body fall asleep but then nothing happens.
I clear my mind with my body asleep... AND NOTHING HAPPENS.
I am getting a bit frustrated but U have perseverence.
Last night I layed in my bed for at least 2 hours trying to AP.
Is there anything Im missing here? Ive tried various methods but the main theme in all of them is mind awake, body asleep putting your body into sleep and leaving your mind awake and open to explore.
Does anyone have some tips and tricks to help me out here?

Thanks,
GP

Tip: Get rid of the concept of time, and tune into the eternal. You have all time.
Feel your body as it vibrates on a low level. Do not fear if you feel your body being crushed or if you start to hear voices. Watch the images play in front of your eyes in detachement. Just wait. Then you will instantly know, and instantly project.

In meditation and astral projection, what works for one, does not always work for another. One has to experiment. The above is what works for me.
