File is too big to manage... How to reduce size?

So a rather simple file of mine went from roughly 200kb to around 15mb.... and I don't know why?  I tried pruge, overkill, audit... to no avail... perhaps someone has some advice on this matter.  It is taking hours to push out the most simple drawings... 

I'm uploading the earlier file (200kb) and the same file a week later  (14mb) for analysis.
