nearly 2 packs of marlboro cigs a day for 22 sad but faithful years i quite 4 weeks ago and panic happened. I bought 1 pack instead of a carton and slowly over several bad days devoured them. The next week my habit was finding butts and lighting but that is gross but then I found myself getting peoples that had been throw out for days or minutes and the brand di not matter. Then I thought about druggies may put something in them for their effects so I took my paranoia to the local store a purchased another pack. I brought them home and made my wife who quite the habit also, hold them and we shared. That was wrong but she is stronger and will only smoke 1 at night. Halfway into my 2ndweek smoking a little2-3 over a day I developed a dry cough but no brown mucous. I got mucinex for a 4-5 day spell and never cough up any thing i then went a couple days with a generic filtered cigar and began getting aweful headaches which I assumed is the stronger nicotine withdrawel? I cannot function so I am back to 5 a day and no cough or headaches? Now what?????????
