I didn't take Chantix but I was VERY frustrated by sleep pattern changes right through until about week 4 or 5. I was so tired all the time and awake at night, etc.
Now it seems to be evening out!
So don't stress as that probably just makes it worse. It will go away. Meantime, I guess you can catch up on reading, drink some hot milk, potter, listen to soothing music...!
