I’m also new to treatment at age 50. Vynase 30 crashed after 3-4 hours? That’s what happens to me on especially stressful days. I started on 20, and my regular crashes were the reason my doc raised my dose–which, unfortunately, has made little difference.
I’m currently looking for a new psychiatrist. (Old one is no longer available, and my GP doesn’t have the specialized knowledge.) If you can find a psychiatrist who specializes in ADD, that’s extremely valuable.
