Just curious I'm on day 42 of no smoking and im only taking 1/4 of the daily Champix dosage which I have been doing for 2 weeks but all of a sudden im so tired feel like I could sleep all day. I have small children and can't. Just wondering if I should stop taking the tablets if im only needing the 1/4 of a dose anyway?? Has anyone been there? I am meant to be on them for another 34 days.
