I have really bad breath and it fucking sucks

I take very good care of myself. I was a drug addict for many years and lost many teeth and took shit care of my teeth. But 10 years ago I read got clean and I’ve been rebuilding my mouth ever since. They are in very good shape considering. I floss almost every time I eat, which is probably because of the OCD. I brush and mouthwash twice a day and scrape my tongue every day. Unfortunately, it doesn’t matter. My breath fucking stinks. I’m on a daily inhaler that I can’t not take that causes extreme dry mouth as far as I can tell. It doesn’t matter what I do I’ve tried everything.
