I've used it to manage pain though I'm not currently using it as I have a prescription from my surgeon that works ok. 

The "introspection" aspect of it doesn't do me any good as it just recalls all my feelings from the past.  That doesn't do me any good at my age.

I'd recommend it for someone under vast amounts of anxiety and stress caused by external factors but not to someone prone to depression.

In the end .. its just an amplifier. You gotta think about it a bit if you want to get amplified.  I'll use it again if I feel that I need to get back to my true self as opposed to getting pulled away by present circumstances. 

 Y'all are all providing some damn good insight on this.
