timeisshort and deteragram, thanks to both of you!
to timeisshort, Yes I have been successful in giving up other addictions but you know they were regarding moral issues but this is a little different. Yes one could always argue that even this affects moral side. Everybody has a weak point and I think this is mine.
to deteragram, You said, "Light cigarettes are just as harmful as regular, full flavor cigarettes. Light refers to the taste, not the amount of tobacco in the cigarette. "
That was helpful because I thought light cigarette contains lesser amount of tobacco.
