Hello, The main effect would be a reduction in blood pressure which may cause dizziness, shortness of breath, weakness, etcetera. Depending on what your blood pressure started off as, you may not notice any symptoms, for example- if your blood pressure is normally high, it would just push it further to normal. If your BP is normally well controlled with medicine, it may push it too low. Some people do not have symptoms when their blood pressure goes too low. If it runs low then do the opposite actions- use a little more salt, increase your fluid intake. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Michelle Gibson James
