I'm sure I've read about this being a symptom of diabetes, having a metallic taste in your mouth but have never experienced it until yesterday. We've been in Holland for a few days and I found it tough to low carb there-very few veggies and bread and chips with EVERYTHING. Since yesterday I've had a nasty taste in my mouth and I wondered if this is due to my carbs ( and blood sugar ) going a bit higher than usual. If anyone else has suffered this, will it go away when I'm back to my low carb diet, or is there another way of getting rid of it. I don't like it!
