Wise advice, Rosebud!

I'd also like to say that if you are taking any medication for blood pressure, always check with your doctor or pharmacist before taking a potassium supplement or using a salt substitute. There are some medications for blood pressure that should never be mixed with potassium supplements as they can lead to dangerously high levels of potassium in the blood that could trigger a very dangerous heart dysrhythmia.
Heart symptoms (pain, palpitations, chest pressure combined with dizziness or sweating) should never be ignored or self-medicated. Always check with your doctor if you are experiencing any symptoms that could be heart related or head directly to your closest emergency room or call for emergency assistance if they are severe.
