Crystals for Addiction/recovery

Long story short, my husband suffers from alcoholism and they quit making his medication to keep him from drinking. He's doing okay for the most part.

Today is our 8 year wedding anniversary, so I was thinking about making him a necklace/bracelet, or something with a crystal to help with recovery. I'm new, only been actively practicing for about 6 months.

When I looked it up it said amethyst, or maybe citrite. I'm looking for more personal experience/advice, other crystals that would be good to use. Or anything else I can do to help.

Thank you. .
