A good friend pulled a cold turkey on me and is now regretting the decision. So I was going on about how I'm feverishly awaiting running to the post office in the morning and how excited I was and how wonderful everyone was here. She thought this was a wonderful idea but asked about how it would show in a carbon monoxide (maybe that's dioxide she couldn't remember) test that she has to take. Since I've never taken one and haven't started yet I was unsure of the answer. If this is a no-no question please excuse me (I didn't see it in the rules but just in case) and delete it or whatever you have to do. No offense taken at all! Thanks!!
