FWIW, I’m on my first week. I switched from the shaker bottle to making a porridge in a bowl in the morning because I had the bad luck to receive a bottle that leaked a bit (they’re already replacing it for me). For me, it’s perfectly palatable, although you have to whisk it a bit with a fork to get rid of lumps, which tend to concentrate the artificial sweetener.
