I'm in the same situation....except my insurance agent is a cigar smoker too.
he told me I can delay three months if I want. I talked to the lady today who will administer the testing (she's a customer) I told her it would be at least a couple of weeks. She said no problem, but she didn't want the agent to give her a hard time. I LOL at that. His kids are babysiting my kids this sat. while we go to a cigar function. I need to lose 15 more pounds to hit the target weight for a "preferred" rate. I plan on being ready by the end of april. I'll quit a week before the test. That should be enough.
One tip, make sure you "fast" that morning, nothing but water before the tests.
It's nice to have a friend for an insurance agent. BTW I'm adding two million in life insurance. The agent sure doesn't want to miss out on that commision, so I'm sure he is looking out for my (and his) best interest.
Good luck.
