i've already had enough

Last week I got in the car and turned on the radio.  It's early November and some radio station was already playing Christmas music.  I only got through half a stanza of 'Santa Claus is Coming to Town' and said to myself, "That's it, no more Christmas music for the rest of the year!"  Stores were stocking up on Christmas items before Halloween.  That's it, I've already had enough.
