Just in case anyone was curious on how the NAC was going... Well, it's not.  It's not the NAC's fault at all- it's mine.  I'm horrible at remembering to take it.   I did great for a couple of weeks, then I started to miss here and there and then I just quit all together.  I figured what's the point if I'm not going to be consistent.  My plan is to try and take it again sometime.  Not sure when though.
