Excersicing helps a lot, no alcohol or stimulants such as cafiene or nicotene, don't eat chocolate, limit
intake, drink something hot when you feel a bit paniced, this is calming. I drink calming herbal teas. Get into Yoga, this helps me sooo much. Have a safe place to retreat to, I like watching the burbs, it helps me keep my mind from wandering. Drink lots of water every day, this helps keep your blood flow level. Don't take blood thinners such as I.B. Profin.
