Here's what wasn't guessed, original phrase italicized:
1. On the road, it's well-advised that you follow your own bag / In the year of the chewable Ambien tab
2. So throw away those lamentations, we both know them all too well / If there's a book of jubilations we'll have to write it for ourselves
4. Is there a powder to erase this? / Is it dissolvable and tasteless?
I kinda suspect only Chad is going to get #2, and #4 is new-ish, but someone here ought to get #1.
