Advice on Dehydration with POTS?

My cardiologist prescribes IV saline through my port. Depending on the weather I get 2-3 litres on top of 2-4 litres orally

I recently spoke with the specialist that manages my POTS… Prior to this provider, my POTS has been completely mismanaged, and I never knew how much sodium to take and when. Long story short, she says that a POTS patient should be taking in at least 4,000 mg of Sodium through electrolyte replacement sources such as Nuun, Liquid IV, Relyte. Try to steer clear of the ones that have sugar, mainly because you end up taking in a lot of extra sugar with the quantities that we need to take. I take the Re-kyte (hydration support) electrolyte caps from Real Salt. You can buy them on Amazon or re-lyte.com They have 880 mg of sodium for every two caps, and in my opinion, it’s a million times easier to swallow capsules and drink lots of fluids rather than drink a ton of salty and odd tasting mixes. I take them 3 times a day every day, and then add tons of salt to every meal, and add Nuun to sparkling water on the particularly bad days!

How much sodium are you taking in as your base?
