Well, sir... You have support from some of the most bad ass quitters on this site in less than 6 hours in! There is no better way to jump in than that.
Here is the thing... And I'm not gonna lie... The beginning sucks. It just does. There is no magic cure, but there are things that can help. Water - like gallons of it. Eating more than normal, and whatever you want. If you wanna eat deep fried butter sticks for the next few days - do it. Exercise to the point where you don't think you can do any more... Then do 50 push-ups. Sex helps everything - lol. But more than anything - utilize this website and reach out! We all went thru this suck period to quit and these bad asses that reached out to you, along with the new members of your group, will climb mountains to help you out.
No pain, no gain... Right? Here is something you must remember... This is not the new normal! Treat this like the flu. It will get better. It won't last. Nicotine isn't the cure... Time is. You know this, and you can do this. Welcome to the best decision of your life!
