Hey Erik, I still have a slight taste in my mouth but not nearly as bad as it was...I'm not sure that's from the Chantix because I"ve heard others say they have a strange taste and they aren't taking Chantix.
Any side effects I had have pretty much stopped, I think the ADR could just be a side effect of not smoking like K Burd said. If this keeps up tho and you think you are getting worse as far as anxiety or depression then do call the Chantix helpline (or maybe give them a call now) and for sure talk to your Dr.
I quit taking the evening Chantix, mostly because I forgot to take it, and I am still just fine, so you might be able to cut down and see if that helps you , but do give them a call.....hope this helps a little...Donna
