What is the best foods for diabetics? how do i manage a sweet tooth?

Low glycemic index: Everytthing with moderation in addition to a low carbohydrate diet is the optimal diet, if you decide an extra amount of carbohydrates you should take more medicine.

Portion control: I think the above answer does well for your first question, but in answer to your second question - you can eat some things that are sweet, so long as you manage how many that you eat. In other words, talk to your doctor or get an appointment with a nutritionist about "carb counting." for more info, see http://www.Diabetes.Org/food-and-fitness/food/planning-meals/carb-counting/.
