Not sure if I should vote on this poll, since I had some "natural" lucids as a kid here and there...

But in my teens, I noticed that I had no LDs for more than a year (and before that had one or two per year) - so I had to practice... To get DILDs again it took me about a month (not sure 3 or 5 weeks so I'm voting 1 to 3 months, as it took me ~4 months to get the first WILD). At the time I could only find really bad tutorials online and didn't really know what to expect (most of my kid lucids were either nightmare associated or very very short)...
