This discussion has really made me think I need to pay more attention to WBTB and spend effort to find my sweet spot. I fell asleep unconsciously last night during a WILD attempt, I most likely didn't get myself alert enough. I have this concern that I won't make it back to sleep since I have traditionally become alert fairly quickly. I think though as the novelty and initial super-obsessive excitement of LDing practice wears off, the background level of alertness reduces and WBTB may take more of an active effort. And don't forget getting enough sleep and a regular sleep schedule.
