I startet using limes instead of lemons and like it so much better. It's a totally different taste.
I also use TheraBreath toothpaste and mouthwash. I use the tongue scraper that's in the TheraBreath package. I put some of the toothpaste onto the scraper, then rinse with the TheraBreath rinse. I buy mine at Walgreens or CVS Pharmacy.
I have NO foul taste in my mouth!!!
Oh, even though I don't eat I still floss daily before brushing and rinsing.
