After a lot of time wondering if I should start a thread or not here it goes…

A little background on me.
I’m a noob when it comes to LD. There’s no doubt about it. I’m starting.
I've had around 20 LDs. One DEILD and the rest DILDs. Half of them didn't last more than a couple of seconds and one of them was the most amazing and surreal experience I have ever had.

Now WILD…
I’m a bit ashamed to say that I've tried probably more than 100 times with no success. Maybe more J
I believe that I've looked more than once into every single tutorial around.
The thing is – I can’t stay awake long enough. I can literally fall asleep in seconds. No kidding. I don’t even need to be that tired.
It usually goes like this… I lay down on my back (I never go to sleep in this position) and start counting backwards from 100… 99.. 98.. Bam!! I lose consciousness before I reach 80 or so. Jolt awake after 1 or two minutes asleep. I try again, same thing.. Once more.. now I´ll use a mantra. Exact same thing..
I have tried everything to maintain consciousness. Binaural beats, mantras, visualization, every technique around. Nothing.
Once in a while I spend the first half hour falling asleep and waking up. And only after that I can stay awake for some time. When this happens there's no way I can fall back to sleep.
There was a couple of times when I reached the point were HI was starting but fell asleep or got jolted awake.
By now I know quite well my REM cycles and I got most of my DILDs after a failed WILD. So I'm pretty sure that I'm timing my WBTB attempts correctly.
Also the problem happens way before the transition period. The only time I reached it I got into a LD (DEILD after a failed WILD attempt).

So by now the thought that I just can't do it is getting stronger. But I'm really stubborn and refuse to believe it when there's so many people here that do it regularly.

What am I doing wrong? What can I do to improve? Is falling asleep quickly that bad for WILD? Shouldn't it be an advantage?
This is long

Please help!
Cheers.
