I have been on chantix (my second round) for about a month and a week. My night time dose makes me the most nauseated and I notice in the morning my lungs have a burning sensation, I have congestion in my head and sometimes my nose starts to bleed for no apparent reason. Has anyone else had these experiences. I do not want to play with my dosage because that is how I relapsed the last time I quit using the Chantix.
