Why the **** do I still craving for smoke

Hi guys, so this is it. Today is 52nd day of being smoke free. I am a lot healthier, I can breath easier, the air smells fantastic and foods really taste delicious for me. But what really bothers me is that I still have that craving for cigarette. Starting from the 7th week (day 45) this craving is becoming a lot stronger and harder to persist. But no worries I'm still smoke free and fighting this nemesis of ours. Just want to share my story so that any of you guys who is about to reach this day can be prepared for this new level of cravings (for me). So it's about a week already this craving bothers me and still hasn't gone. Let's see if I'm strong enough to get through this level. Really feels to light up a cigar while writing this. Are there any of you guys experience this? Looking forward to stories & experience from people who already pass this 52nd day journey of quit smoking. Regards. Oh and I go cold turkey for this journey. Thanks!
