Soylent and coffee is not a good start to a day. Neither provide morning hydration. Sacrificing your health because it's fast and easy is something my younger version used to believe too. And yes I have consumed Soylent in the past up to 3 times a day for months on end.
I was talking about food, not hydration. I drink 24oz of water with breakfast as part of drinking a gallon a day. I track my daily hydration with an app on my phone. 177 days in a row and counting.
