Considering the fact that you’re recovering from some pretty restrictive eating patterns I doubt 2000 calories is enough for you.
Like pod, I drink something with all my meals. I’ve tried not as I’ve read plenty about how it hinders digestion but I just don’t find eating nearly as enjoyable without something to drink. I am seeing much more regular elimination patterns anyway so I suspect as the metabolism improves the gut starts working better the fluid consumed with food has less impact. Though I do still avoid plain water and prefer to drink something with significant calories.
