First, save the session by another name (in case something goes horribly wrong)

Now, put a marker at the end of your song (so you don’t delete it by accident).

Double click on the zoom tool (shows the whole session including all extra time).

Now, drag directly over/on the timeline ruler with the mouse from the very end of the visible session area backwards to just before the marker you inserted (all tracks should now be highlighted).

Hit < Control Delete > (deletes all regions and all hidden layers of automation break points).

Now double click on the zoom tool again and your session should be pretty much back to the proper length.
