If you find yourself sneaking, then why are you doing it?  Whether this means eating a thing, writing a thing, doing anything at all whilst no one is looking, examine that.  Did we not say the other day that guilt is an indicator of misalignment?  Be impeccable with your words and actions.  If you cannot, be willing to shine a light on the cause beneath the behavior.  It may prove enlightening. You are so very loved.
