I am almost 60, female. I never get enough sleep. I can go on sleeping until I force myself to get up. I have various twitches through out my body which can include fingers, hand , knee , foot , leg, etc. They are quick twitches but they are getting to be more often. I often have trouble speaking to people, which includes stuttering and my jaw locking up before I can say what I am thinking. Until this past year, I have never had a problem speaking to anyone. It is a major part of my job. Does this sound like the beginning of any specific ailment or just getting older?
