Is random, reoccuring sudden episides of shakiness, nausea, weakness in legs, lightheadedness, dry mouth, cold hands, headache & body aches a sign of diabetes? my father has it, so was wondering how likely it is that i could have it...?

Hypoglycemia: Hypoglycemia episodes come to mind. In a nondiabetic this would be a reactive type hypoglycemia which occurs an hour or so after an ingestion of sweets or heavy starch foods as your body responds by secreting too much insulin. Your blood sugar first goes up, but the insulin drops it too low. Checking your blood sugar during the episode would be helpful.
