I never drink vodka. I don't like it. I drink water. I try to drink 2 litters of water every day. I don't like energy drinks either. Those drinks are not for me. They are unhealthy. Yesterday I drank three bottles of beer. Now I am drinking water the whole day. What are you drinking now, sitting at the computer?)) When I drank the three bottles of beer I didn't get drunk. I wasn't drunk at all! I was OK. Have you ever drunk vodka, by the way?! My friend had been drinking vodka for five years before he finally made his mind to stop. So, you better never start drinking vodka!
