I’ll give you the same as I did for someone else, in a sense.
I firmly believe you should write your dreams down b/c it helps with a number of areas for increasing lucidity and the chances at becoming lucid. But if you don’t maybe you can just find a quiet time during the day and read some of your old DJ’s, the dreams specifically where you experienced an LD and remember how good and fun it was. Really remember. Try and day dream the lucid dream and see it that works.
Sort of a personal problem, the only thing I can think of is that either your too tired or just un-motivated. As for solutions you probably need to force yourself to write down your dream as soon as you wake up.
