As changes become more stable, they will become your new norm and will remain with you through your lifetime.  It’s like learning how to read or swim – once you know how, you can’t not know, although you may get rusty.  However, your brain is living tissue and can get thrown off by stress, chemicals, hormonally changes, an anesthetic, head injury or other challenge. If this happens to you, a few booster sessions will help your brain return to its good place.
