Difference between SM, WM and DSMI?

[Shannon]

Thanks!

One more question:
I understood the product information this way: DMSI results/ effects will go away after a special time of not using the sub. The SM/ WM results will last "forever".  Is that correct?

WM/SM effects are DESIGNED to last forever.  How much they last depends on a lot of different variables, including how many other programs you use, how long it's been since the last time you used it, how correctly you used it and how much you accepted and executed it during your run.  

DMSI relies on two specific approaches to achieve it's goals.  One of them (dealing with the things holding you back from success with the goals of DMSI) can make long term or permanent changes, and one (the aura/energy manipulation) will fade away after a time of not using it anymore.  

Generally, you'll want to refresh whatever program you use periodically.  Stuff like AM/SM/WM may need to be refreshed every 12 to 24 months.
