I don't know how this will go but I want to do it, I have done much harder things in life and ready to take this on.
You've made an great step, but it doesn't sound like you're 100% committed. If there is even 1% uncertainty in you, this addiction will seek it out and exploit it to bring you back to the can.
Even the title of this intro (Day 1, He goes nothing) seems to indicate a half-hearted attempt. Quitting is EVERYTHING. It's just that simple. When I get up in the morning, I remember I am still an addict because I plan when I'm gonna post roll here. When I brush my teeth at night before bed, I remember I'm still an addict because there is no shit hung in my teeth. There are a lot of opportunities between those two, and I take advantage of every one to enjoy the pride that comes with quitting.
We've all been through some pretty tough stuff, but I can't say that there are any that were harder than this. You may be causing yourself a problem by underestimating the task at hand.
I know, regardles of what disaster hits me today, I WILL BE QUIT when tonight gets here. So, if you "Don't know how this will go", it very likely will end in failure. Get engaged... completely.
