Answer:
The only thing you have to do is stop recalling dreams, and you will forget them. Just think about something else when you wake up for 1-2 minutes, like : "what do i have to do today, lets make a plan". After this 1-2 minutes of shifting focus your dream will fade away from the short term memory and then you wouldn't even remember anything about the dream.
Do this for 2-3 weeks and you will probably stop having/remembering lucid dreams.
