?
a taste of your own medicine
?
every cloud has a silver lining
?
get something off your chest
?
go down in flames
?
hang in there
?
lose your marbles
?
play second fiddle
?
under the weather
?
back on one's feet
?
go bananas
?
tough nut to crack
?
bigger fish to fry
?
kick the bucket
?
no-brainer
?
knock someone's socks off
?
head over heels
