Yeah, i absolutely agree with Indeed, down to how the natural LDing skill is attained. I do not like these devices that claim to give you lucids purely because part of the thing that makes lucid dreaming so great is you have to attain it yourself- if you had lucids nightly just because you purchased something, i wouldn't find that half as enjoyable.
Also, you most definitely should not give up just because you haven't had a lucid in a while - Give yourself a break, from 3 days to a couple of weeks where you don't worry about dreaming at all. Heck - give Dreamviews a break, if you'd like. When you come back, you should/will redouble your efforts at your technique (as you are going for a natural approach, i'm going to assume DILD). Question your reality whenever you remember it; a method i use is throughout the day "realise" i am dreaming. With consistent efforts, you will also get consistent lucid dreams. Seeing as this method involve your subconscious coming into the play of the repetition of your technique, it may take a while (it took me two months to have consistent lucid dreams with this method) but it is totally worth it.
