I don't think your alcohol level makes much of a difference.

The Microcyn or Vetricyn is more of a treatment that triggers your system to fight off the infection. It kills the topical infection then triggers your body to push the infection out. Polysporin is just a topical that helps prevent infections more than it stops existing infections.

Benzos are greatest risk during the first 72 hours after injury. Not as much of a problem at later times.

I would encourage you to get professional care to learn skills for dealing with anxiety. We have had others who self-medicated their anxieties with alcohol. It is tough to get and stay sober without learning skills to reduce anxiety. Maybe somebody can help you change your thought paradigm. Many of us have benefited from Christian faith to deal with these issues. Others have suggested other ways to try to reduce anxiety levels.

It is a tough road, especially if you try to do it alone, but the benefits to getting free of anxiety are worth the effort.
