I smoked for many years & tried a few times to quit but failed miserably. Tried many different techniques including various medicines - nup, nothing worked.

A mate of mine who smoked as much as me got some hypnotherapy years ago and it worked a treat for him.

Managed to quit early last year by going cold turkey as I really wasn't enjoying it any more. Not bragging, but I haven't looked back and don't really miss it (well, maybe a bit hehe)...
