Low potassium? Maybe. But high alcohol? Oh yeah!
The recommenced daily allowance of potassium is 4,700 mg. To get this, you would need to eat 10 to 12 bananas every day! This could be the reason why you don't feel better - you still are not meeting the amount of daily potassium requirement. Look into taking supplements.
A couple of days ago I went to a neurologist who checked my blood after I complained of blurry vision. The test came back low potassium and he said that that was the cause of the blurred vision. It's been a couple of days and I have been eating bananas and drinking Gatorade like mad and the vision isn't much better. Wondering how long it should take to get better if it is potassium deficiency.
