I quite 5 months ago from one day to another, no preparations, nothing..Just spanish cojones. I smoke for 18 years like 20 cigarretes a day. I only can recoment to stop smoking. Your body and your mind changes completely. My mind is sharper, way sharper. #cigarretsmakeyoustupid
I do think cold turkey is the best. It also prove you are ready! Just get your mind into the right thought process, and go for it!
