I'm not sure where I read it, but up to 33% of people who drink up to 4 cans of soda a day develop depression. Fruit punch drinkers have a higher chance, with 38%.
WELL DOESN'T THAT EXPLAIN A LOT
Seriously, whenever I found myself in my room, I was always in a saddened mood, as if something was always dragging me down. I usually drank 4 cans of soda a day thinking I was just tired, trying to get caffeine into my system. But, no. I was actually screwing with my brain somehow. So, I am limiting what I drink from now on. Tis' a shame, I love Pepsi and Fanta :'(
