I am a 76-year-old male with gMG, and I take 5 mg of prednisone daily. I wouldn't want to take more than that, but it would be hard to take less. It gives me energy and moderates all my symptoms, in conjunction with my immunosuppressant. I know of several others who are on "maintenance doses" of prednisone: 2.5 or 5 mg, with few side effects. More than that is risky, long term. But don't jump the gun. As long as the mestinon is working, it's your safest option. If it eventually loses effectiveness or the side effects become intolerable, you and your neurologist can devise a backup plan, which might involve prednisone and/or an immunosuppressant. We all need to guard against "medication impatience." There is no perfect med, and nothing that will make you completely normal. I am satisfied with "good enough." When it isn't "good enough" anymore, I know it's time to see my doctor.
