Some docs don't know much about it, even though it's been approved by the FDA since 1994 to combat alcohol abuse. If you have Amazon Prime, you can watch this excellent 50-minute documentary about it for free: https://www.amazon.com/One-Little-Pill-Claudia-Christian/dp/B01F5U541E
Here's a brief video on it:

I'd suggest you read the book too:

Aside from that, it takes most people 6-12 months to become indifferent to alcohol again, like they were before they got addicted to it.
Did your doctor tell you to take it every day in the morning or at bedtime?
