Diabeties and Chantix

My son is 13 (14 in August) 6ft tall and around 260lbs. We used to do Martial Arts together and that kept him active but when I stopped he didn't want to go anymore. Sensei asked if he would "help out" at the Summer Camp next week to try and get him back in the door (a genuinely wonderful man) and with major encouragement from me and hubby he agreed. When I asked him if he wanted to come back to the Dojo with me for Fitness Kickboxing, he didn't want to. As much as I don't want to, I know I have to quit smoking (again). I have been putting it off but the smoking is interfereing with my workouts, I get winded faster etc etc etc. I wish I could be a casual smoker like so many people but if I smoke one I am smoking the whole damn pack. Anyway, I made a deal with him, he wants me to stop really really bad, so I told him if he joins FKB with me I will quit smoking. Of course he said I should quit anyway, smart ass that he is, wonder where he gets that from lol. I told him you want something and I want something so thats the deal. He agreed. So starting the Tuesday after he helps out in the Dojo for the Summer Camp he is starting FKB with me and I am quitting on that Tuesday. I started taking the Chantix yesterday and here in lies the problem. I finally got my diabeties under control without pills and it is almost in complete remission, ranging from 90-140, 140 if I have too many carbs that day. Taking the only one Chantix pill so far has spiked it to 166 in the A.M. where it should have been around 90ish and 2 1/2 hours after lunch to 206 where as it should have been around 140ish because I had wheat thins with my lunch. So today I took a 1/2 a diabetic pill along with the Chantix and a half hour after taking it it was 109. I guess I'm not sure I want to go down that road of my sugars being out of control again and having to take the pills again, but I made a deal with my boy and I can deal with it for 2 weeks. Nicotine is out of your system in three days, I have to take the Chantix for a minimum of a week for it to take effect and make me "not want" cigs, and for at least 4 or 5 days after quitting to make sure the nicotine is out of me. I'm curious to find out how long after I am done taking it will it still affect my sugar levels. Ok thanks for listening to the ramble.
