I got my first lucid earlier today on my third try, and wrote about it in my DJ. It was really quick, and I fell into the trap of waking up from excitement.
I used the WBTB method, but it was actually a Mild? / dream induced. I used all 3: mantras, wbtb but I only regained consciousness once I was in my dream.
Going to keep at it. I hear it's a good sign, even when one wakes up too early. :)
