I still don’t have one since I’ve studied it for 2 months…Really to try one, or even make it as a habit, or something like a game
It took me about one month. I was trying really hard. I only got really good at it 5-6 months later.
Took me around 2 weeks to have my first full lucid dream
These things vary sooooo much from one person to another that it’s pointless to compare or make statistics. I got lucid on the first night I tried, but even now after 5 years and many many lucid dreams I consider myself far from being good at it 
I just want to know how you guys tried…Maybe I started losing interest as I haven’t had one lucid dream
Within 3-4 days of learning about it. But that’s because I was very excited about the possibility and was thinking about it non-stop. I have had lucid dreams since the first, but I’m still trying to figure out my personal formula to achieve them regularly. I try to LD every night but fail 95% of the time.
Approximately 1 year. I gave up on trying to get a lucid dream, and the very next night I got a lucid dream. So, keep trying (not too hard!) and don’t lose hope 
I think I had mine about six months after learning about it.
It was about a week after I started. I wasn’t really going for LDs at that point, though. I was just improving my DR.
It took me a couple of months but I never have been able to have long LDs or have them regularly. I gave up on lucid dreaming for a few years but now I’m trying again and after 2 weeks have had none.
It took me about 2 weeks of actually trying to have my first one, and it was a decent one that lasted a few minutes. Since then i’ve only had one or two more semi-lucid dreams, no full ones, although I haven’t been trying as hard.
My first LD involved no effort on my part. It simply just happened about 2 months after first hearing about lucid dreaming. I suddenly had the urge to do an RC in the dream despite the fact that there were no dream signs, and became lucid. I guess that as long as you want to have a LD, you will eventually have one, no matter what.
