Even if you can't dedicate a full day to LD, try to set aside an hour before bed to read through books about LD practice or online information about dreaming (not really general forum posts, but things that get you thinking about lucid dreaming). Other than that, you should take some time to read through your old recorded dreams, which can be both fun and helpful. In general, you have to get your mind to say "wow, dreaming " and that should get you back into the swing of things.

All the Best,
