It´s perfectly normal to want a cigarette after 5 days of abstinence, your quit is still young and i´m afraid you will want a cigarette for a long time. Hell, i want one. But after the withdrawal it becomes easy to manage the need for one. At one point in time you will achieve confort and It´ll become a nostalgic need more than anyting that you can control easily. Until you get there, keep on noping! Good luck!
