My number’s up

You know how someone’s always saying he can’t get a certain song out of his head? Like, he won’t be able to stop singing “I’m A Little Teapot” over and over, either silently, inside his mind, where it feeds on the grey mush of his brain like a ravenous maggot, or aloud, out in the open, where it tingles his tongue like particularly aggressive Pop Rocks? Well, that’s what’s happening to me lately, except, because I’m such a kooky non-conformist, the thing I can’t get out of my mind isn’t a song but a series of numbers.
For instance, I cannot, for the life of me, stop thinking these numbers, in this order, and, yes, in these colors (not these exact colors, but I’m not going to search high and low for more precise ones, because I am not a mental patient [yet]):

1 2 4 7 9 3 5 6 8
I blame the color on my synesthesia (Google it! It’s non-curable! But the doctors say I am expected to live at least through the end of the year, which is super!) and the numbers (not their ordering, just their fixed place in my mind) on sudoku. I fear I have become addicted to it. And, like with every other worthwhile addiction, I think it’s best if it’s shared with other people, so I don’t/won’t have to suffer alone. Take, for instance, my addiction to love. I started that whole trend, and then Robert Palmer did a whole song about it, complete with a bevy of backup beauties who, at the time, bore an uncanny resemblance to — yes, that’s right— me. And I won’t even get into my heroin addiction, which got so out of control that it spawned an entire “look” and lifestyle that attained the status of “chic”.
Aaaanyway, for what it’s worth ($1,247,935.68), sudoku has taken me over — mind only (the soul is soon to follow, and who knows about the body) — and since I don’t want to suffer solo, I want to bring you down too. You see, if I must, by dint of the insidious allure of sudoku, writhe in a bizarre blend of mathematical pain and pleasure, then sodoyu.
P.S.  I will not tell you what 1 2 4 7 9 3 5 6 8 tastes like. But yes, thanks to the synesthesia, I can taste it as well. Nifty!
