I’m sorry, Frank, I’m not really schooled enough to be able to give you specific information on dosages. I find one pill tends to work for me, but everybody is going to have a different reaction. If your nurse thinks it’s okay to test it again, I’m sure it’s fine. She knows a lot more than I do! In the meantime, I’d try to get a lot of exercise so you can burn off some of the stress. That tends to help when I’m getting nervous about an upcoming flight. You can do this! 💪
