If you’re not opposed to medications, bupropion (brand name zyban) helped me. My cravings lessened almost immediately. Nicotine also feels like it has little to no effect since I started, which was honestly kind of a bummer to find out when I fell off the wagon.
I get medication isn’t for everyone, but just putting what worked for me out there. Funny enough, I didn’t even start taking it for smoking cessation. That’s just one thing Bupropion can be used to treat. It was a two birds one stone kinda situation.
