I used AMAS for several years to help with a few medical issues I had. I fought diabetes for nearly 15 years before giving up and going on meds I couldn't fly with. Prior to that every time I switched meds it usually required a waiting period before I could fly again. My AME was good about wavering most of them down to 14 days. AMAS is a great resource. I was lucky in that my company paid for it but even if you have to pay it's worth it. They have a phone conference with the FAA medical folks every week and go over the cases AMAS is working on.
