Great choice. And 5 days is a great start!!! But now comes the hard part...staying quit. The Nic Bitch will get more and more clever trying to trickfuck you into caving...no sleep or dip dreams, triggers you weren't aware of, etc.
The key is posting roll. Giving your word to us and keeping it. And establish an emergency plan...a strategy for how to ward off craves and numbers to call (your July bros will help with this but feel free to PM me for mine if you want). I didn't use numbers, but my motivation was a better life for me and my family. So I kept a copy of the Kern Family story with me.
Then, I recommend living on this site early on. Read everything you can. The better you understand your addiction and what you and the others on here are going through, the better you will be able to fight.
You will succeed. Failure is not an option. Stay strong, stay quit, brother!
