a bottle of softdrink saves my day

oftentimes i prefer to drink soda instead of water after meal to satisfy my thirst. i know that it is not healthy and water is still the best liquid to intake to maintain a healthy lifestyle... (tama ba?).. but aside from this, the reason why I'm so addicted with soft drinks is that, it helps to lower my temper and keeps stress away. i don't know if it is just a psychological effect or caffeine drives away the bad spirits every time i'm down.. cheers!!!!!!!!!!!!!!!!
