Day 8 smoke free!

Hi all, I’m on day 8 smoke free using champix tablets once daily as I find the night time tablet keeps me awake so I just take one in the morning. I’ve found quitting this time around ( I’ve tried many times) so much easier. I don’t understand why but it seems to be more habit than a anything else for me this time, I don’t miss them I don’t get as many cravings for them but I’m still constantly thinking about smoking. I am concerned about weight gain but dealing with one thing at a time for now and getting rid of this addiction is my main priority for now. Any tips or advice would love to hear it..
