The toughest part was your decision to quit. Now it's just a waiting game to make your mind and body accept the new reality of not having steady doses of poison.
Hang tough. It won't be easy for a while, but it will get easier, and then much easier still, to the point where you won't even think about it for days at a time.
But that is in the future, and today is what you have to deal with. Read as much as you can here and participate and you'll realize you're not alone and everyone else is dealing with similar struggles and withdrawal symptoms, whether physical or mental or both.
If I can do it, anyone can, including you.
Best wishes for a strong and permanent quit!
