I didn't have my first lucid dream until about a month or so after I started recording my dreams. And even then it only lasted for a few seconds. Last time I became lucid was when I looked in a mirror and saw my face had a bunch of holes in it (O_O) and the dream literally collapsed around me and I felt like I was being sucked back into consciousness.

To make things easier, become familiar with your past dreams, they can be very entertaining to read and will increase your dream recall even further.
