How long do you stay with the beginner one before moving to a longer or more 'advanced' version??

I have insomnia and have been taking sleeping pills for years. Whenever I stop them I have periods of months with little sleep and high anxiety. I just want to unwind and be able to sleep on my own again.
Hey, good work! It ain't easy.
Some people have been using this track for years, you don't really "have to" move to advanced if you're getting good results.
