Hey everyone. I'm new to become an ex and quit smoking 4 days ago. I have been on Chantix for 3 weeks and it hasn't really helped with urges as much as helping with mood swings. I can definately tell a difference in how calm I am this time quitting when compared to other attempts at quitting without Chantix. I wish it helped with the urges more but any help is good! Well good luck to you all with Chantix!
