I would not waste my time with that lawyer or either of the AMEs you talked to. HIMS is for when the FAA determines you have an abuse problem, which would be hard to argue when it’s been 10+ years since those incidents. In the end, just set up an appointment with an AME for a 3rd class and see what happens. You’ll create a MedExpress account and fill out the pre-appointment questions. Read them slowly and carefully before you answer. The question that probably pertains most to this subject is 18v. Read this website before answering that question: https://pilot-protection-services.aopa.org/news/2022/april/01/the-notorious-18v If you have to answer yes to 18v, and that causes consternation with the AME and he says you need HIMS, etc., then the worst financial case is you’re out $150 or so. Don’t get sucked into paying thousands to lawyers.
