Getting more than 10g of Sodium per day and I feel better?

Hi guys, I have never posted before, but I found out I have POTS around 2025 May after going to the hospital for throwing up 15-20+ times per day without any reason and blood work showed that I am low in sodium even though I was consuming normal/health diet at home. All of my weekdays meals consist of fermented veggies + rice/patsa + eggs/steak/chicken and nothing else.

I exercise regularly. I lift fairly heavy for my weight and play pickleball for 2-3 hours at a time and sometimes I am literally swalling 4-5tabs of Himalayan Salt tabs during my workout bc I get fatigued easily and I immediately feel better after.

Last night I played 2 hrs of Pickleball outdoors here in NYC and my mood and energy level was just dead after getting home. And I know I still got over 6-7g of sodium yesterday.

This morning/afternoon, I got about 3-4g of sodium in one sitting and started immediately feeling BETTER. I also usually get no upset stomach from eating this much Sodium as long as it is from Himalayan salt pill/tabs.

Does this mean that I need to up my Sodium a bit more on days like yesterday?
