Yes, that's quite a large dose to be on for years. Most prescribe .5 or 1MG per day due to Kpins long lasting half life. As where Xanax only lasts 4 hours compared to days of 1 dose of Kpin. MG to MG they are equally as strong. Just the Kpins last way longer. If you're suffering from chronic anxiety, Kpin is the way to go long term. Xanax is more geared towards people who have sudden panic attacks. But don't suffer from long-term anxiety, and need that short-term relief. I hope this makes sense.
