Welcome.
Forget the 24th. Quit today.
Here is a link to your Quit Group. There are instructions for posting roll at the top of the page. Posting roll is your promise to not use nicotine for the rest of the day. Post roll early in the day, and repeat tomorrow, and every tomorrow afterward.
Honestly, putting it off til Sunday gives you five days to lose steam, and make up excuses to keep dipping and smoking. Quit now, post roll, keep your promise. Get to know the guys in your quit group, and swap some digits. Reach out when you need help, be willing to support when one of your brothers or sisters needs help.
In case I haven't made it perfectly clear, quit now. Flush all tobacco down the toilet. Rinse your can, and throw it away.
