I get a horrible taste in my mouth, too, not constantly, just every now and again, and for about three days at a time. For instance, it showed up on Saturday, (my birthday, of course!!), and I find that eating sweet things really doesn't help it. It is certainly rather metallic - I've not had children, so couldn't say if it is the same as what you get when pregnant! Fortunately, the taste doesn't seem to be the forerunner of a headache, as with some of you. I find it actually puts me off my food - a disaster, in my case!
