I agree, 15tsp = around 60g! In hypoglycemia you'd be expected to consume around a quarter of that. However, I feel that its better to over correct a hypo than not do enough. 60g is definitely excessive though!! People like to use different things for hypos, the best ones recommended though are around 100-150ml lucozade or full sugar coke (the red bottle, wondering if this is where the whole red thing has come from?), 4-5 glucose/dextrose tablets, or a few jelly babies. The idea is just to have around 15g of fast release sugar. Some people choose to literally eat pure sugar but I can't say that appeals to me.
