I started taking it right before christmas and quit the next week as supposed to. Only slipped once on New Years and it was pointless because I didn't get that ahhhh feeling because of the chantix so that's good. My problem is I am exhausted. Just exhausted. It is a struggle to do things. Anybody else go through this? Thought maybe it could be my body detoxifying but I don't know. I guess I just need a little encouragement.
