There is another thread in the Newbies' Questions subforum you might find interesting: Strange sensation/taste in my mouth, is that normal?

I knew I was (finally) in ketosis when I had a metallic taste in my mouth that won't go away. My LC friends tell me I'll get used to it and won't notice it after awhile.

I confirmed the ketosis with the ketostix (btw, someone suggested carefully cutting them in half so you get twice as many, and I did--they are kind of pricey!)

HTH
