Hey! Welcome to dreamviews. I am always excited about someone finding out about LDing. I would recommended Exploring the World of Lucid Dreaming by Stephen Laberge. He is "the doctor" associated with LDing. His book explains everything. It isn't very expensive and has all sorts of awesome info as well.

Did you find anything about the adrenaline? I often use adrenaline when I am working and found a way to get it to come naturally. Did you find out if it is harmful to do often?
