Last time you posted when you were not smoking (albeit for a mere 16 hours, so basically a night's sleep and then not smoke until the afternoon) and then ignored people's interest when you fell off the wagon. Why would people support you now if you're just going to ignore them again if you fail?
Anyway, good luck.
BTW, you failed last time because you didn't want it enough. Nobody was holding a gun to your head. There are measures you can take to increase success, like not keeping your lifestyle exactly the same minus the smokes. eg If you sit around a computer or tv all day with a beer in one hand...the other is going to be a cig more than half the time.
cut the beer at the same time. Get a gym membership
Also, the more times you fail, the more you expect yourself to fail, so if you start this without being fully convicted, your chances of failing are great and then next time you plan on quitting, you'll remember that you failed yourself last time and you now accept that as something about yourself, that you allow yourself to fail at things.
What has happend in the last 7-8 months that makes you more convicted in quiting than you were back before when 16 hours seemed like a lot? I believe that most people lack the inner will and desire to do hard things, from quitting smoking to long term weight loss, to taking good, honest care of their finances. Most people seem slaves to their impulses and carnal urges, unable to rise above them.
