wake up about halfway through your sleep. you get more rem in the second half of the night. as we all know rem is when most of our dreams take place. before electricity humans slept in a different pattern we slept first sleep and then second sleep meaning we basically woke up through the night then go back and finish sleeping later. so you should try that. if you go to sleep at 11 wake up at 3-4 for 20-60mins then go back to sleep. it seems to work for me, however i sleep at 3:30 am then my roommates wake me up at 7 when they go to work then i usually get non lucids in that second half but no lucids yet but that's why we're all here right. and remember with enough willpower and perseverance we can make anything happen.

I see you have trouble falling back asleep when woken might i suggest to lay on the ground, yes the ground, for 20-30 and genuinely try to sleep on the uncomfortable ground and then after 20 lay back in your bed and do the exact same you will be so comfortable in comparison to laying on the ground that you will fall asleep very fast. it has worked for me in the past.

don't worry either 2 weeks is hardly a long time to try and get a lucid. I've been at it much much longer with no luck yet although i got close one night
