You seem to be doing well Art, and more to come im sure.
I would just say, wbtb can be tricky, and making it a part of your sleeping habits can be a chore. Finding the end of your deep sleep cycle is important to calculate when your chances are the best. Usually it goes for about 4-5 hours and your chances are much higher after that. After a while of using the alarm, you may even begin waking up at the time naturally and with little effort. As long as its a consistent habit, the body typically has no problem working it out.
It took me a while to learn wbtb on a consistent basis, but its a very effective way of improving your dream experience.
Keep it up, and more dreams will come
