How long do i MILD for before going to bed?
All day!
When doing reality checks, tell yourself you’ll be lucid once you are asleep. Once you are in bed fall asleep with that thought on your mind. Easier said then done though, depending on how fast you can fall asleep. 
Like at night when I repeat the
mantra in my head. How long do I do that
Basically until you feel your SC has gotten the point. It’s great if you can do it until you fall asleep, but you can stop earlier if it’s keeping you awake. Just make sure you don’t get to the point where you’re mindlessly repeating a phrase.
True, it’s not so much about how long or often you repeat the words, the point is to believe. (Agent Mulder anyone? lol)
You have - or rather your SC has - to truly believe, almost know you’ll become lucid. That’s why it’s importaint to imagine yourself becoming lucid, maybe visualizing it, rather than just repeating empty words.
Ok thanks, i repeated it falling asleep last night and fell asleep fast, but no LD’s…
