Drip Drop is the best hydration powder that I have ever tried. My husband who is a Type I diabetic had a bout of vomiting and Diarrhea a few years ago and normally that would mean a trip to the emergency room because of his blood sugar going very high. I gave him 2 doses of Drip Drop (2 packets equal an adult dose) about 6 hours apart and administered extra insulin. I check his blood sugar every 2 hours. After the 2nd dose, his stomach and settled and his blood sugar was almost normal. This stuff can be a literal lifesaver! It also works on less severe cases. The taste is great! I can't find the lemon flavor locally so I order from Amazon and always keep some on hand. I can't praise this product enough. Try it and see for yourself
