What were you addicted to? If it's booze, did you honestly think it would be easier?
Maybe it's a good thing quitting is a b!tch for you this time. Like the analogy in the Big Book about the guy playing in traffic. You were insane to jump in front of the bus again. Hopefully you won't do it again.
I can relate to 15 minutes at a time cuzz that's how I did it.
Good Luck and God Bless.
