Hello everyone! I'm new here and just been having rough time in general. It's my 6th day without smoking so far. I've been on the Chantix 28 days now and there is some pros but yet CONS . I've notice I have been losing my temper so quickly now. Also insomnia ,headaches, dizziness, urinating alot, extreme racing thoughts,heart throbbing, paranoia, vivid dreams , tight chest ,etc. I know you're suppose to experience new changes when quitting smoking. Just feels like I'm losing my mind! Any one experience this or worse?
