DO IT NOW.
These delays can last YEARS.
What do you think is going to happen in those years?
Do you think everything bad that's going on in your body just stops while you think about it?
IT DOESN'T.
If you've just recently failed, GET BACK TO QUITTING ASAP.
The longer you wait, the easier it is to keep smoking.
Waiting is nothing more than an excuse to keep smoking.
