I don't have my prescription yet. Long story. But I decided to clean the mountain of junk on my dresser and behind my jewlery box was a bottle of Chantix from my last quit!!!! If I hadn't been trying to delay smoking I wouln't have found them 🙂 They are 1mg. tablets and I know the first few days you are supposed to take .5mg. Does anyone know if I can cut them in half? I'm so excited I found these!!! They don't expire until March either!
