Welcome to the site, backnforth!.
It's good that you recognise that you have a problem. That's a start.
Cutting back or drinking 'in moderation' just won't work..I've tried that, and it didn't work.
As for the prescription meds, it depends what you're on, as most docs will tell you that some meds can be addictive. If you're just talking about the sleeping pills, and you're following the dosage guidelines, then that's fine.
