Hi Skeggy
I think the official line is that you shouldn't use it but if you must then only chew it for a couple of minutes and then discard it. I think this is because it could cause cravings etc. I have to admit that I chewed gum throughout and didn't have any problems but I guess it's it's a case of trial and error. You could always try breath freshner. I've heard Gold spot is best.
The joys of Ketosis!!!!!!!!!!!!!!
