What are the cheap, delicious and low-fat healthy drinks?

I want something low in calories. 0 calories. Let me tell you something. The drink does not exist. Except drinking water. This is what I drink. I happened to take a picture by the bed. When you get used to this. You'll still feel emotional. Drink it for a month and your taste will be corrected. I promise you can't drink a carbonated drink. You have a terrible headache. The actual measurement is effective. If you can drink this thing like I do.
