Yup. Your tastebuds are waking up, and it sounds like they're cranky. 
I went through a couple phases of tastebud resurrection myself. And sense of smell for that matter. I became really sensitive to tobacco smoke -- I can smell it upwind from a hundred feet these days. I didn't discover things I liked I now hated or anything, but stuff started tasting and smelling a lot more vibrant. Especially spicy foods. That became painfully evident (literally) when I doused a pizza with some green Tabasco -- the mildest Tabasco -- and it was suddenly intensely freaking hot where I used to be able to handle it no problem.
But everyone goes through it a little differently, and if your tastebuds and sense of smell are bringing back the bad things first, all you can really do is power through it and learn what your new taste and smell profiles are like. They may yet change still and stuff you hate now but liked before you may like again at some point.
