Desperate, look into the Soberlink device.
In mediation with my AH, I asked for him to carry a Soberlink device. This is a device that connects to a Smartphone, or you can rent one that is a standalone. You can create a schedule that requires him to blow into it, and his BAC is uploaded and you receive a text update. My AH will be blowing into the Soberlink 3x/day during the days he has the kids. He gets text reminders and if he misses blowing, I get a text. If he misses blowing completely or is drinking, I go pick up the kids. Cost is $210/month plus $100 activation. Anyway, suggest you look into this.
