Good to hear, I find its useless to try anything unless I am already beginning to feel SP and such, at least vibrations. I usually just start off just relaxing, controlling my breathing, etc.. I'll get vibrations in 5 minutes, and thats a good time to start for me.

This holds true with almost any technique for me, for example in a FILD (Finger induced) If i start the movement before vibrations set in, it becomes so repetitive that by the time I need to use it as an anchor on reality, I've forgotten about it and will slip into a regular dream.

Just try to find the balance where you can progressivly fall asleep, almost naturally, but still experience some tactile sensations (or whatever you are using that night). If you think or try to hard, you often wont fall asleep.. happens to me quite often tbh. But im getting better and better at it, just takes some fine tuning.

Try to stick to one method a night for now, so you can be consistent in your results.. Trying 5 things a night, on random nights, where you sleep for different periods wont help. If its obviously something isnt working, you can try another.. but by this point im usually to distracted, and just assume fall back to sleep normally, maybe set an alarm for 30 mins later or something, and try then. You wont get much sleep, but it gets you back to square one fairly easily.
