Lol it doesn't matter what time you go to bed, you should still wait from 4 to 5 1/2 hours or so before you try WILD. Some people say they can do it when first going to bed, but they're probably very advanced or extremely lucky, and I don't think they manage to do it often.

You should spend some time reading tutorials on this site, or just go for broke and get Steven Laberge's Exploring the Word of Lucid Dreaming.
