That sounds like an awful dose to have. I think I'd rather just be a happy, non-anxious layabout than that. Did you have to go through a phase like that while weaning yourself off of anxiety as a driver of your own productivity?
I've been working on managing my anxiety for several years, and my productivity has been getting worse as my anxiety lessened (which was counterintuitive to me). That's how I ended up figuring out I might have ADHD.
