How NOT to use subliminals

[Shannon]

Ah very helpful, thanks. If I only use them in 15 minute sessions, is it the same? (15 Alpha/Theta then 15 Beta) or does it have to be 30 mins?

You just want to make sure you re-set your brain to beta after using alpha or theta if you're going to use them every day in order to avoid training your brain to stay there. That would be at least 15 minutes of beta, and always make sure beta is as much as or more than the amount of time you use the other one.
