I tried a good B-complex vitamin and that has helped. If I know I have to be in a crowd of some sort, I will take a benedryl or dramamine to help stay calm. I also started eating fresh fruit and veggies. I also take brocoli capsules. Supposed to help prevent breast cancer also.
I'm so sorry you experience these attacks, they are so devastating to a social life. Good luck with the remedies that have helped everyone here on the forum.
