I have used chantix two other times before and both times worked really well. (But being stupid I started back again each time) any how the last two times I got the box with the white tablets 0.5mg. And then the blue tablets. This time my doctor gave me the prescription in a bottle with only the 0.5mg tablets and states to take one tablet twice a day. It's for a month and I also have a refill on it. Why did I not get the box and also the blue tablets?
