Panic attacks - anyone suffer?

Shortness of breath (hyper-ventilating), dizziness, pain down one arm (I forget which, the other arm means you're having a heart attack*)? Sleep apnia?

I used to get them in my late 20s, turned out I'd developed an intolerance to caffeine... Nine months of suffering was over as soon as I stopped drinking tea, coffee and Coke... Go see a doctor tomorrow, better safe etc...

• My last panic attack involved my GP telling me I may have had a heart attack instead of a panic attack so he sent me straight to the hospital for an ECG... That's when they found out about the caffeine allergy...
