Nicotine Gum Addict Comment that shattered me...

For those who don't know I maintain another site called NicotineGumAddict in which i share my love hate relationship with the evil addiction i have for Nicorette gum.
I of course take comments there and I was particularly moved by this one:

I've been chewing the gum for probably 20 years!! I'm the daughter of a doctor who used to write me scripts for it when you needed one; so I got it for a 3 dollar co-pay....I went off of it a couple times (and back to smoking)....Today is my second day trying to quit the gum (I buy Kroger brand; it is the cheapest); I feel this is as difficult as quitting cigarettes themselves. I could go on and on and on. My question is have you found any literature on the long term effects of the nicorette???? I'm a nurse, and figure that it HAS to be bad on the cardiovascular system as it causes vasoconstriction. I just can't find it written anywhere and I NEED confirmation that it is BAD for me, so that I can rationalize quitting for GOOD! Any other helpful tools/ sites???/ideas????

If anyone has some thoughts please put them here or over on the NGA site..
