Feel weak: There are many reasons. I would be certain your blood or potassium intake is not low. Have blood K checked with precautions being followed by person drawing blood: no fist clenching and remove tourniquet then wait 30 seconds before drawing tube for blood K. Not doing this can lead to a false normal K when it is low and making u tired and fatigued.
