Hello my Name is Alex and iam a Waterdrop addict! This is really a great way to increase your water intake. I was very sceptical about this, because usually all this stuff is nasty sweet and taste fake. You can always put sweet in but not take it out. Waterdrop is not sweet at all and taste straight up amazing, its all natural. I love it! I put one of those cubes in a 24oz bottle of Water, I add nothing else. Thank you Waterdrop, for giving me a healthy drink and give me a way to increase my water intake. I like all the flavors but youth is my absolut favorite so far. I highly recommend you give it a try. I hoping to see more flavors. A promoting sleep option would be great to see as well. Also more all day options would be great. I saw you have a new one (focus) guessing this is also a wake you up one. I just ordered this one and wait on its arrival (can't wait to try it) . I buy a lot waterdrops and still keep running out. From order to arrival it's about a week. So long story short... I love it, try it, It is amazing, delicious and truly increase your water intake, highly recommend!
