Re WBTB, how long is best to do so.

Appreciate different people, different times but in the Advanced Lucid Dreaming - The Power of Supplements book he recommends taking the supplements & getting straight back to sleep asap.

Other views are 30 - 60 minutes, so any views on this & as as add on.

3 nights back I was staying somewhere, I woke up around 5.30am, got dressed, drove home, which took about 45 minutes, had a fag & then went back to bed. Had a 21mg nicotine patch on but that was all & then had a pretty good lucid within a couple of hours of sleep, so can that be considered a 60 minute WBTB with all that driving & being fully awake or was I just lucky on that occasion?
