Why is my spreadsheet so large and sluggish?

My spreasheet is built as a consolidation from 3 other spreadsheets sent to
me each week by 3 different users. Almost overnight, my spreadsheet went
from 12 mb to 30 mb and portions of it are very sluggish now. For example,
when I scroll is is very choppy and slow.

Anyone have any ideas what would cause this? Thanks
