Still few side effects so far have surfaced from taking Champix, even after increasing the number of pills that I have to take daily. I still suffer from some light insomnia which is highly annoying. A new side effect has popped up over the last couple of days; increased urination . It doesn’t bother me at all during the day, but I’ve been waking up in the middle of the night to go to the bathroom. Combine this with the insomnia and I’m finding myself being very tired in the morning. Being tired is also making me a little cranky at times.
