Was not a good start, 4 to 7 days delivery turned out to be 14 to 28, but it arrived. I was going to send it back with the delay however I opened the package.
I have no idea how these things work but on my first day I went from 40 cigarettes to 5. Whatever the science is behind it, it works. Day 5 and no cigarettes at all. No withdrawals, no cravings and no nicotine therapy.
So even if your FUM is late, don't send it back all hot headed, from a 35 year chronically addicted smoker to hope in 5...
