I quit on chantix but then when stress came off to the store I went to get ciggs then back on chantix I believe the 3rd time I got suicidal quit taking it and that stopped. Now I take it PRN because it helps my agitation from not have a smoke so I take 1 every 3rd day.
It does help and allow yourself to try it before everyone tells you they went psycho on it. It really does help and helps me.
