Don't ask me why.. But when i finished reading this all i thought about was that song by shakira "addicted to you", i guess it'll fit u to sing it >=).
Now.. If u quitted, means you're strong! Remember what Ben Parker (RIP) said: " with a great power, comes great responsability".. Maybe about trying to quit it for real. One day at time, one step at time.
Also.. Winter is coming, which means we all need some extra pounds :P
