It doesn't even need to be a challenge....setting the example and getting sober for yourself is entirely under your control. Challenges, ultimatums, comparisons, etc, are not only beyond your control ( you cannot "makes" someone get sober ) but they can actually cause more problems than they solve.
Certainly encouragement of each other and support is helpful...but at the end of the day only you can get you sober, and only he can get himself sober.
