Can you give some more details on your nicotine delivery method, I'm trying to quit smoking this year ( actually today is day No. 8 since I haven't put nicotine in my blood ) but I'm super interested in the side effects. I work from home and it seems I can't focus on developing so easily and get distracted even more these days.
