water making me sick

Jessie • Stay at home Mom to a wonderful daughter. Married to my best friend. After 4 years TTC 4 rounds of IVF proud twin boy mama. Loving life each day as it comes.
Drinking plain water literally makes me sick. I bought Powerade and doing half water half Powerade. And I am drinking 100% more then i have been. Urine output is better and my nausea is gone. My only concern is Powerade isn't good for the babies. Any advice??
