Tongue betrayed by food

So the last couple of days everything I eat has a bitter aftertaste.  It's a bit subtle so it's taken me those couple of days to be sure that I am really tasting this all the time.

Apparently, sometimes Asian pine nuts can give this effect, and nobody knows why yet, though there are theories, and yes, I ate a handful of pine nuts I had been saving in the freezer, and now I think I must throw them away.  They weren't as expensive as Italian or North American pine nuts (which you can't find anyway), but I guess pine nuts are just going to be out of my reach if eating the affordable ones might randomly give me a pervasive bitter taste. The articles I read said it goes away in a few days to about a month.  Meanwhile, as I become more aware of it, it's becoming more annoying (at first I thought maybe the particular food I was eating was too old to eat, though it looked, smelled, and tasted fine and I knew it was okay).  Things taste fine when I first put them in my mouth, but after a couple of bites it starts, and after I eat it gets worse and worse for a while.

And then there's the phenomenon, the inverse of the placebo effect, that once you know something's happening it gets more and more noticeable after that.

Oh well.  I suppose, given my extra storage, I actually could give uop eating, relatively, for a while.  But I don't want to.  and given my personality and the fact that food tastes fine for the first bite or two, it will be difficult not to unconsciously stuff my face trying to chase the bitter away.  Must not be unconscious around food, I guess.
