Post-Lucid Dreaming

I am just wondering if I have to keep writing my dreams down in my dream journal after i have my first lucid dream, and if I should keep using inducing methods after my first LD. Anything would be greatly appreciated.

In my opinion you should.I believe it can save you a bit of dry spells which sometimes come unexpectedly and no one knows the reason.I think keeping a diary and keeping practicing prevents it.
It still depends a bit on tech you use.Some are said to be practiced all life or at least for long periods of time so you can really master them(i.e. tibethan ones).
good luck
