Hey Andy welcome to the site. I'll be 24 in august and have been doing the same thing as you the past 8 years, except with grizz wintergreen. Either way, the first 3 days of quit suck! We have all been there and you need to embrace the suck to remind yourself in the future why you never want to go through the first 3 days of quit again! Keep your head down, post roll and give your word, and get through one day at a time. It's pretty simple, just gotta execute. And it gets much better my friend...you gotta believe.
Glad to be quit with ya brother, if you need anything shoot me a PM.
Ian
