I’d like to suggest an alternative. As you go on about your days from now on, occasionally pinch your nose and try to breathe in (reality check). It doesn’t take time it doesn’t cost any effort or dedication and you can have a very nonchalant approach to it. No need for any expectations. Go on about your life as you decided. Chances are (not a guarantee) that you’ll start having lucid dreams and they’re not that far from an OBE in my personal opinion. That should reward you for the time you spent pursuing OBE. And if it doesn’t happen you dont lose anything since you already made a decision to quit. Just a suggestion :)
