Well, actually I have given up (non-herbal) tea, but the same principle applies to lemonade. Boil the sugar in the water for a greatly improved taste.
My sources (Dr. Hulda Clark, et al) say that artificial sugar induces diabetes and greatly worsens it. Based on her books, I gave up tea, and within a few months, the problem in my lower legs disappeared.
Alternative health rules!
You're kidding? Dr (Ph.D not MD) Clark is an out and out fraud.

One of her wacky claims:
All cancers are alike. They are all caused by a parasite. A single parasite! It is the human intestinal fluke. And if you kill this parasite, the cancer stops immediately. The tissue becomes normal again. In order to get cancer, you must have this parasite. . . .
This parasite typically lives in the intestine where it might do little harm, causing only colitis, Crohn's disease or irritable bowel syndrome, or perhaps nothing at all. But if it invades a different organ, like the uterus, kidneys or liver, it does a great deal of harm. If it establishes itself in the liver, it causes cancer! It only establishes itself in the liver of some people. These people have propyl alcohol in their body. All cancer patients (100%) have both propyl alcohol and the intestinal fluke in their livers. The solvent propyl alcohol is responsible for letting the fluke establish itself in the liver. In order to get cancer, you must have both the parasite and propyl alcohol in your body [5:1-2].
I hope you don't own a syncrometer or one of her zappers.
