Hi Bme.3,
I drink a lot of chicken, veggie broth, SF jello, Protein shakes crystal light, or other sugar free drink mix, and sugar free popsicles. Be sure to take your vitamins. I use the Tespo liquid vitamin machine, and Calcium patches. As a man we are not used to the sips every 15 mins and so that is the hardest part for me at least. I found an app that sends me a alert to remind me to drink. Premiere protein shakes are great and high in protein. If you have any questions feel free to ask, and good luck to you.
