WBTB is a tool used by virtually any lucid dreamer. That means that WBTB is useful for people who want to DEILD, DILD, WILD, etc. The advantages of performing an WBTB are those of clearing your mind during the night and strengthening your intention of lucid dreaming. Some people medidate or inspire themselves in order to have a DILD, while others relax and prepare to WILD in the middle of the night due it being easier since you fall asleep faster but since you woke up and "cleared your mind" a bit, you're less likely to loose conscious so easily.

I totally agree with paigeyemps, DEILD seems to be the right thing for you. As an extra tip, you can always try to schedule a WBTB to a specific time and wake up every day. That makes it much easier and more likely that you'll wake up on your own and perform DEILD even more easily. Good luck
