I am 6 weeks off traditional ciggs and trying to taper down on the nicotine. Started with 12mg and 30 days later mixed 50/50 12mg & 6 mg = 9mg. I noticed a significant mood change the first week of this change but have since adjusted. I am curious to know how and how often others have tapered down. Is there a specific amount of time that needs to pass before decreasing levels, a suggested timeline? Thanks, Denise
