My bird has been going to Slimming world & has lost 3 stone in 13 weeks. They even asked her to run a center as she understands the whole system really well & is inspiring to all the other members. The problem is she's had this horrible breath since she's been on diet & I don't want to kiss her. I assume it's because of less eating & different types of food. Is this a common thing & what's a good way to deal with it other than brushing teeth & gum every 5 mins.
