I started Chantix a few days ago. I'm on day 4, about to up my dosage to 1mg per day. I feel as if I have super concentration powers for the first couple hours after I take it and I have a lot of energy! It seems to be putting me in a better mood. I haven't had any of the bad side effects as of yet, and I'm hoping (optimistic) that I won't. Has anyone experienced this while taking it? All I have read is people feeling extra tired, not perky like I'm experiencing!
