                        Hi,  I have the same symptoms as you have and am diagnosed with SMS.  I have had the aanti-GAD antibody test and EMG.  There are supposed to be 3 kinds of SMS.  One is simular to ours where just the legs and falling are affected.  Also before I was on medication I couldn't yawn or roll over without my abdomin tensing really bad.  I am able to do most things around the farm without help, but need to take my medication.  I have had this condition for 5 years and am 52 years old.  I do not have Diabetes or Thyroid disease.  Good Luck.  Judy
