Flavored water - Mio and Crystal Light ok??

I am having a hard time drinking so much water. I was ever a thirsty person to begin with. Now having to drink practically a gallon a day seems nearly impossible. Not to mention when I'm nauseas it's REALLY hard to force water down my throat. I've been adding Mio and crystal light to my water. Does anyone know if that's a bad idea?? I know the whole red dye thing is an issue but it's the only way I'm able to stomach so much H2O in the day! Does anyone know if it's safe??
