I gave up on giving up. I just vape now, low voltage pen style vaporiser, menthol flavouring. All the benefits of smoking, drastically reduced damage to my body and wallet.
I quit years ago using the nicotine patch, 3 descending dosages. Each time I switched to a lower-dose patch I had a bad day. That included yelling at people and kicking the wall in my office. It was ultimately worth it.
Try replacing a smoke with exercise. The endorphins released from exercise replace the desire for nicotine. Worked for me forty years ago. I'm still addicted to working out.
I’m proud of you for trying to quit. It’s not easy, so I wouldn’t worry about what strangers think.
