Smh I feel nauseous as hell. But not throwing up or anything. I have no appetite really, but I do get thirsty. And my pee is normally light yellow but now it's some what dark... what does that mean? Dehydrated possibly? I've been drinking a lot of water this morning. But mostly ginger ale these past two days.
