I drink Fruit2o its artifically sweetened. My favorite is Diet A&W root beer, tastes exactly like regular root beer and leaves no after taste at all...I use Sweet & Low for tea, and I get sugar free kool-aid at Wal-Mart that is better than Crystal Lite flavor wise...SugarLike is my sugar of choice for baking, their website is www.bakingbutter.com I use their white and brown sugar...Tell your brother to X out any and all white foods from his diet, no white rice, potatoes, pasta ot bread, use brown rice, sweet potatoes, wheat pasta and breads....Also get and take cinnamon capsules, and an herb called Gynema Sylvestre, good for diabetics....I hope this helps.I nearly forgot, I suck on sugar-free popsicles constantly at night, don't gain any weight and the red and banana ones are my favorites. He could keep a bunch of them in his freezer..I too drink diet Peach ice tea and its great...
