Trying to not drink tap water
For a long time I mocked people for saying that there is "bad" water or that it tastes different from place to place. Since 3 months ago when I started my diet, I have only drank water. I definitely have to agree with them now. Different water (especially tap) can taste quite bad.
My dietitian told me that I need to drink 2 liters of water per day. I found this difficult to keep up with so I grabbed an empty 2 liter and filled it up with water from my fridge. I only drank it when I was thirsty, and by the end of the day, I felt terrible. My head hurt and I was very spacey. I've tried this exact same thing with bottled water, and I feel nothing but well after it. I checked online for the water quality inspections for my area, and we are the worst within 4 counties.
So this brings me to my actual question. I'm trying to convince my parents to buy me gallon jugs of water. Of course they are somewhat ignorant and mock my request by answering "there is plenty in the fridge or sink". I've got them semi-convinced so far, but I just don't know what to tell them.
Any advice would be great!
