I AM A 42 YR OLD MALE. I HAVE HAD TYPE II DIABETES FOR THE PAST 5 YRS AND TREAT IT DAILY WITH INSULIN. IN MAY 1998 I WAS DIAGNOSED WITH CONGESTIVE HEART FAILURE AND IN OCTOBER A HEART CATHETERIZATION DETERMINED THAT I ALSO HAVE CARDIOVASCULAR DISEASE. MY DOCTORS HAVE CHOSEN TO TREAT MY PROBLEMS WITH ALOT OF MEDICATION. I TRIED ZYBAN FOR 2 MONTHS TO QUIT SMOKING, AND ALTHOUGH I HAVE REDUCED MY SMOKING HABIT FROM 1 1/2 PACKS A DAY TO ABOUT 1/2 PACK A DAY, I JUST CAN’T LET GO OF IT ENTIRELY. WHAT ELSE CAN I DO? PLEASE HELP ME!!! I HAVE BROUSED THE NET FOR SOLUTION AND HAVE FOUND SITE LIKE chantixhome.com WHICH SELL PILLS LIKE CHSNTIX FOR ANTI SMOKING . SINCE THE PILL COST A GOOD ANOUNT I WAANAAATAA ATAO KNOW IF THEY REALLY WORKS, SHOULD I GO FOR IT OR NOT???
