He was telling how his grandfather quit one fine day coz he was feeling breathless after climbing stairs and he quit, he was saying even he may do once he decides...not all ppl have withdrawal symptoms...it depends from person to person... quitting gradually is good but who quit suddenly also don't have problems... again it depends on mind and body as everyone is different
Even my friend quit suddenly and my boss too, but they say how hard it is once they do it, and sitting idle at home doesn’t help at all!! It depends on person to person and feel when they have so much issues going on, it’s better he gradually gives in or once he gets busy with work he gives up!
