Someone else posted something similar to this the other day, but I can't find it, and I didn't read it at the time.
I've had this bad taste in my mouth for about 4 days now. It doesn't taste 'metallic' like google always tells me, it just doesn't smell good at all. I keep brushing my teeth obsessively, which clears it for a little while, but it comes back. I don't have a particularly bad cold, but I feel like i've got something in my throat which isn't so nice.
Help! It's not nice.
