Welcome Zack congrats on making this decision. It's not easy, especially for young guys, but I assure you that it won't get any easier by waiting and letting your addiction get even more ingrained in your life.
Looks like you found roll call, which is the first big step. That post represents your promise to stay nicotine free today. For today, nicotine is entirely off the table for you. Make that same promise tomorrow, as soon as you are reasonably able (WUPP - Wake Up Piss Post). Do that enough days in a row and you will be free. You'll always be an addict, but you don't have to be a slave to it anymore.
Let me know if I can help.
