I find that if I have caffeine I will get the flutters. Also I believe it's been when my blood sugar has been lower than 4. So make sure that you eat regularly and try and cut right down on sugar and caffeine. It really does make a difference.
I think the first panic attack I had, 7 months ago now, was caused when I delayed my lunch and ate about 2 hours late. This was the first time I experienced the dizziness and feeling like I was going to die.
I hope these thoughts might help someone.
