I trained myself also to have lucid dreams, but haven't had one for a while. I think it would be a good timing to get back into it now that I no longer have early getups for a job - I feel that has been an obstacle to really focus on it when the first thing in the morning is about rushing to work, doesn't give room to recall dreams well.
I had the most success when taking a nap after school for a few hours, sure I would only get back to sleep at 2-3 am and wake up a zombie the next day but those 2-3h were way more hours lucid. :p
