I am on lexapro and smoke about pack if lm lights 100s for about three years. I have an interview and was told they will be also checking for nicotine in screening which includes patches, gum, etc. Interview is in 5 days and figure that is when they will do testing if i get the job. I quit smoking at about 11am but put on a patch and chewing regular gum like crazy. Would it be better to take chantex?How long does nicotine stay in your system? Can i take any meds to help symptoms? Have seen increase h20 consumption, but im very nervious, gittery, and massively craving cig. Suggestions?!?!?
