My situation was like yours...

I've been trying to induct my LD for 1 month, and nothing (I've just improved my Dream Recall and now I think it's excellent&#33, but when we are trying to have our LD we don't realize that our Recall ability is so important as our LD induction ability... That days I thought that if I had one Lucid Dream I'll remember, but now I know if our Recall is not in shape (hehehe) we can easily forgot our LD!!! EASILY! Probably the first one is SO exciting that we never forget it, but when you have more... it starts to depend a lot of your DR.....

So, take a break as I did, I stopped thinking about LD for 1 week and after that I had my first one... Think about that you have nothing to lose...
