There are quite mixed response from the online research I did last year. Some say it helps with morning sickness, some say best is just plain water.
I am using the filter alkaline jug and convert boiled water into clean alkaline water to let me wifey drink last year when she was pregnant. Boiled water not so cooling and have been continuing till now. Unfortunately, unable to share if it will affect since we had a MC last year. But I am sure not due to the alkaline water
