Try Wellbutrin... that worked well for me, the generic... the key is to take that and smoke only 2 cigarettes a day, one in the morning and one at night, before you go to bed.. than after a month or two, get rid of the one you at night, by that time your nicotine level has dropped 90 percent of you were formally a pack a day smoker... and you are almost there. The withdrawal symptoms will almost be non existent... it took years of smoking to get here.. so it isn't like most people can just stop one day... It's a day at a time...this uses rewards... so you don't panic..I also kept the cigarette in my glove compartment of my car, so I physically had to go get one...I also got a vape pen and low level nicotine that I would hold onto when I was driving, which was a trigger and would take one or two puffs if I felt the need . much better than smoking a whole cigarette... I got rid of the one in the morning with my coffee after 2 months, that was the hardest one... and I haven't smoked since September of 2022... and have no desire to ever smoke again and can't stand the smell of cigarettes anymore.. good luck. Keep trying.
