Is it safe to drink kool aid while pregnant?

im asking this question because my water at my house is nasty! It takes gross unless its added to something. Iv been drinkin kool aid every day. It helps my morning sickness. I hardly get morning sickness now that i drink it. But i go threw like a 2quarts of kool aid a day. Its only a cup of sugar! Is it that bad? And another question! Im only 6 weeks and i have absolutely NO appetite for food! Some days i do and some i dont! What can i do? This is my first pregnancy! And i cant take big pills but is it okay to crush the pill and take it? Also is there chewable prenatal vitamins? And do they taste bad?
