Make a self-control roll when presented with a tempting morsel or good wine that, for some reason, you should resist. If you fail, you partake – regardless of the consequences.
Make a self-control roll when faced with the “need” to break unreasonable laws; if you fail, you must obey the law, whatever the consequences. If you manage to resist your urges and break the law, make a second self-control roll afterward. If you fail, you must turn yourself in to the authorities!
