Workbook started running very slow

I have a workbook with several sheets in it. Nothing too fancy, some conditional formatting, a few drop down lists, 3 simple macros and a little bit of code on two of the three sheets. As I was building it it was running really fast, the macros would happen almost instantaneously. The data that moves when you select "CLOSED" on one of the drop downs would move to the other sheet without even a blink.

Now when anything moves, or a macro is run it's doing it in slow motion, slowly going through each step before completing. I'm not sure what I did or at what point is started running really slow. Maybe it's just my laptop??? The workbook is too big to upload...can I rename it something that will make the file size smaller so I can upload it for review?

Thanks all - love this forum!
