When the moon is waxing, how does the position of the Moon in the sky change from one night to the next? (Does it get farther from or closer to the Sun or does it stay in the same position with respect to the Sun?

I know for a fact that it does not stay in the same position, so if anyone tells me that, you need to get shot.

I have been smoking 2-3 packs a day for 18 years now and I'm 29 years old. I was just diagnosed with COPD and I finally decided to stop smoking. My doctor put me on the patch and the stop smoking pills both. My question is this. I read all the instructions and it said that it's very easy to get nictine overdose and not to smoke while taking the patch or the pills but I can't just go from smoking 2-3 packs a day to nothing. So I'm wearing the patch taking the pills and smoking about 1 and a half packs a day now. What are my chances of developing nicotine overdose and how quickly will I start getting the symptoms? Thanks for your help.
