Has Diet Coke (in a can) changed in the past few months?

As a kid, Diet Coke was all my mom ever bought, so I spent years getting used to it.

I dont drink much soda anymore, but it seems the last few times I've had a can of Diet Coke, it's just not good. It seems more bland than ever before. I don't seem to dislike any other sodas more than I used to.

Anyone else notice this?
