Hi there ! You must have been very lucky with all those LD’s, I mean you’re a natural 
. I had problems with waking up too. I sometimes dream the same dream more times, but in a longer period of time, like a year or a few months. The best things which truly worked for me are the following:
-
When feeling the dream is fading and you’re waking up or something’s not right with the dream stabilization, just let yourself fall on your back telling yourself in your mind that you will wake up in a FA. Those are the best dream stabilizers for me ! (FA’s)
-
Let yourself reinvent a world when feeling the dream is fading. Simply close eyes and fall down through the ground. This also worked pretty well for me, or jumping into a mirror also worked.
[spoiler]
The bad thing is that I always ended up in a creepy place (skeletons and stuff, cause I was thinking of another “world”, you know), but that’s not a big problem [/spoiler]
- Now this, I never tried cause I always forgot and I would do this in an extreme situation where all my other methods fail. Simply do a DEILD (Dream Exit Induced Lucid Dream). [Method can be found here]
That spinning and rubbing your hands never worked for me, even though I tried them 
.
Good luck, and hope you get your LD skill back !
