How should I do this--

I have decided to try and quit smoking today. I have been smoking off and on for 16yrs. I am afraid to do it on my own (cold turkey) also I see so many adds and blogs about several diffrent aids so im confused on which I should try. There's Chantix,quit smoking, patches (tried b4),stop smoking, nicorret, cold turkey, phone and chat and books and so on and so on.... I am wondering if someone who is maybe familiar with these sites has maybe formed an opinion of what might help people more. Its my first day and the cravings havent hit me really hard yet SCARED!!
