Are you drinking enough water during the day? Eating enough veggies with Sea Salt ? Do you know if you are low on Aldosterone?
I suffer dehydration very quickly due to low Aldosterone.
I drink 2.5-3 quarts of water daily, plus I use a salt call Hawaiian Bamboo Jade Seasalt (other Sea Salt s did not help me), I put this on all my foods.
I have to stay away from foods that act like diuretics, plus I just recently realized high potassium foods cause me a lot of problems with dehydration.( For me the potassium takes over the cells and kids out the water that makes me dehydrated as well.
