SUBJECT: Low Potassium. MESSAGE: I have been taking Melitonion to help me sleep. My PC has prescribed 20 meq of potassium for low potassium level.  He has since increased it to 40 MEQ as my potassium level is still under the normal levels. Should I stop taking the Melitonin to help me get to sleep at night.
