Ever since my 2nd thyroid lobe was removed I experienced cramps every night from about June of 2003 until about 3 days after I began utaking 2 medi cramp pills a day, along with @ least 2 bottles of water with electrolytes & 3 bottles of regular water. Now I only cramp if I somehow not drink the 5 bottles of water & then the cramping is much less severe. Thank you for your product.
