i just did cold turkey,, with no help from anyone. what did it for me was, i had a massive heart attack10 years ag, it just happened in the morning, n i woke up 2 days later,, not knowing that i had a heart attack.
it's when the doctor gave me the nitro pills,, that i knew they were not kidding. it took alot,, to not pick up a smoke cause i was smoking 2 packs a day at least.
U r the one that has make ur mind up, if u want to quit or not. u can spend money on items to help, but U r the one that has to really do it.
the best of luck on quiting
