Trying to quit smoking

[Jesus0171]

I have noticed the last time I quit it was impossible to do it cold turkey but my doctor recommended removing 1 cigarette a day. I tried all the medications and they didn’t work or I had too many side effects. 
I have been smoking for about 40 years and it’s extremely difficult to quit. 
I am going to start by removing 1 a day as that really helped me last time
