I've tried quite a few different remedies and medications and found Beta Blockers to be the best thing for when I get really stressed or have a bad panic attack. They are normally used by people with high blood pressure. I guess they must work by stopping the body from getting so worked up.

I've never had any ill effects or problems with them. They're not a sedative and you won't even notice that you've taken one.

Ships in harbour are safe..but that's not what ships were built for.
