Today begins my 4th week, and I'm still in induction. I have noticed for the past week and a half that I have this really bad taste in my mouth. I keep brushing my teeth, but it's not going away. It's a stale taste...I guess not terrible like I said in my subject line, but certainly yucky enough to notice. Has anyone else experienced this? I wonder if it's related to my diet or just a coincidence. Thanks for any response and feedback!
