It helps me to make sure my knees are locked and even casually leaning a little on the counter a little to take some of your weight. I wear long socks and have heard compression socks and/ or tights help with the blooding pooling in our legs. When working at a restaurant, I always drank water before any type of other drink I wanted. Stay very hydrated. Good luck!

Knees ARE NOT LOCKED ****

Get a personal air conditioner or fan that you wear around ur neck my aunt with POTS and a condition where she can’t sweat

I would consider asking to be put on some more medication if you’re open to that idea. I’m on midodrine right now and I barely get dizzy anymore, but medicines work differently for different people. Also stay hydrated, take salt or salt tablets, wear compression socks. Maybe flex your leg muscles and kind of walk in place to get your blood flowing. You may be able to ask for a stool or something I’ve never had a full time job but they may do accommodations like that

i know it's overstated but drink a lot of water it can rlly help with this

Cooling vest

Electrolytes lots of electrolytes I like the lmnt brand

Drink lots of water, get a personal fan, worse case scenario eat fries loaded up with salt.
