Also good to know---stop caffiene, and nutrasweet intake, AND if you 're taking certain Birth control pills or Estrogen supplements---DON'T let them "kid" you---they CAUSE angina -like symptoms w/ extended use!! READ the fine print! Also READ a great resource book by a women GYN, Dr. Christiane Northup, MD--"Women's Bodies, Women's Wisdom"--an A-Z resource book of scientifically documented info. (helpful to men too.) The Birth control pills I was taking to "balance" my hormones sent me to the emergency room on several occasions, always told it couldn't be from them---but one nurse said "get off them, I've seen too much of this in too many women..." I did---my hormones balanced themselves and no more angina! Nurses should be the DR.s and we need to educate OURSELVES. Good-luck!
