I just tried the counting thing and boy on average it gets real weird around the number 60 for me. Around 60 My mind starts randomly thinking about other things, I'll forget numbers and drift into a dream. Tried twice and both times the same thing happened. And it was much easier to get lucid. The second time I did it I basically said once I start forgetting how to count I will open my eyes. And when I did open my eyes I was in a dream.
Lucky! I wish that worked for me. The best way for me to fall asleep is to just think about everything and anything until I fall asleep.
