When was the last time your blood levels were checked? What was the last test result?

I would not get Gatorade - there are far better electrolyte solutions available these days. Smart Water is just water +electrolytes, sans sugar. There are also drinks that do have sugar but do not have as nearly as many additives and colorants as Gatorade. Or, if you have dried fruit at home, you can put some in a pot of water and boil it down. That would be your potassium-rich homemade electrolyte solution. Very tasty if you squeeze a few drops of lemon juice into it. Far healthier than Gatorade. But still, the most important step now is to get a blood test. If you are seeing a new dr and are on lithium, a blood test would be ordered anyway - it is the standard of care. But if you won't see that dr. for awhile, just go to urgent care and request that test there. The lab gets processed quickly and the dr. or NP in the urgent care dept would have the answer soon.
