I don't drink a lot of fluids and it's so hard to try to train my body to drink water. I don't know why but the only time I'm ever thirsty is when I'm eating dinner, so that basically is the only time I drink any fluids is at dinner. I have a water bottle that I bring to work yet I only take a few sips a day out of it. Even while working out I don't drink that much! How can I fix this issue?
