Taste test?

I need some help here. For a few days now, I’ve completely lost my sense of taste for anything sweet. I can eat a Hershey’s bar and it feels like I'm just chewing on straw—zero sweetness there. At the same time, everything tastes salty, almost like I just swallowed a mouthful of seawater. What could be going on? I'm not even on any medications... maybe it's Candide?

Yeah... and it’s like, even when I just drink plain water, it tastes salty to me. Like, a legit salty flavor. Plus, any food I salt normally doesn't even taste salty at all. I don't really have any other symptoms, everything else seems fine, I guess... anyone have an idea what might be going on?
