what is the best way to relax or fall asleep very fast ?

[ld1]

i have problems with sleep. especially now when i am trying ld. In beginning i concentrate on breath (in -1,out 2,in 3 out 4) and then (about 50) i feel that my legs and arms are heavy an warm, and i start to loosing them, not feel them, and then i am starting to think "HURRAY I AM IN TRANCE, I will make my ld, Hurray", and then i am so excited that my heart starting to beat like 120bpm and can not sleep anymore. and whole night is shit without sleep. are there some methods to fall asleep very very fast to make mild or wbtb later ? just to paas through n rem and other phases until rem ? or are they some methods to just go to bed at 10.00pm and go fast and directly into rem ? maybe some NLP or time line ? + i thing that i have ADHD in my legs. sometimes when i try to relax without moving legs i feel so terrible pain in them that i have to move them. pain and tension.and if i move them - few minutes ok and later again.... shit.
