I have a life insurance test coming up mid March & need to make sure I'm clean. Will be 30 days without smoke come test time (Shocked myself that I've made it almost 2 weeks so far without smoking so far!). I've smoked daily for 25+ years, am 6'2 & 300 #'s. From what I've seen on this sight, its not likely I'll be clean in 30 days because of my body mass even though I've started excersizing daily. Will likely use N2's dilution method, but have some questions. What is the purpose of the aspirin? would adding salt help or hurt? Should I dilute more because of my size, or less because I'll have been clean for 30 days by the time I test? I have to get this right as family is riding on it, wife can't work due to chronic pain & I'm the only income. Policy will be pretty big to make sure they are taken care of if something happens.

Any help would be greatly appreciated.
