It's really cool to try new things, even it was just a bottle of water :P
Recently I've been going back and forth to Apella Superstore like 4 times weekly to get my Oxigizer water. It claims that it has 15% more oxygen than regular water. So since I suffer from constant headache, I was advised to drink oxiginated water as it helps the brain to have more O2, bla bla bla. It's really refreshing when I drink it Super Super chilled.
another thing to try for those who have headache, is Pocari Sweat. It's sold everywhere even in pharmacies.
