Discretion has to do with being discreet or with making choices. A lot of people hear it and get influenced by the quite different word “digression” which is used to label instances of people wandering off the point. The result is the nonword “disgression.” The expression is “you can do it at your own discretion.”
Also wrong but less common—and pretty funny—is “at your own desecration.”
