Better tea than coffe. But best way is to get a half of litter of water in the morning. Of course, not all at once. But the first glass immediately after waking up and then to breakfast the other. After a night your body is dehydrated and need hydration. Therefore, water is the best with liquids in the morning. Coffee runs contrary deodorized the body. But I know the temptation, I often drink coffee in the morning because I like it and it helps me wake up faster. However, the water is much healthier.
