Lemons are interesting. I bought lemon juice and planned to take it regularly, but couldn't tolerate the acidity. My vitamin c has citrus bioflavonoids in it. I am not a fan of papaya, molases, or oranges, as they have too much sugar. I like using cinnamon when I want a sweet taste. Cinnamon is antifungal and antibacterial and has no sugar(just a small amount of complx carbs). Licorice root is also sweet and has no sugar.
