Are you drinking at least 1/2 your body weight in oz of water per day?
Make sure you do. I like to carry a bottle with me throughout the day so I don’t forget. Also, be sure you drink at least 8 ounces of water with each meal. It helps you feel full and keeps you hydrated. If plain water is difficult right now try adding lemon or cucumber to it for added benefits.
I have read that drinking a glass of room temperature water with lemon as soon as you get up in the morning has a lot of extra health benefits.
