I have some gigabyte memory of sitting on fence... quitting smoking or not quitting ? before taking decision to quit.
Shall I quit smoking? , possible/not possible, If I fail? how can I cope up routing work... you know all such questions make us indecisive. Want to quit smoking but sitting on fence.
I urge those who are in this mental frame, please come out, and decide to quit. It is doable. Trust yourself.
Many Ex on this site, who are successful in quitting would agree. Go for it ! All the best...
