Recently the hair on my legs has stopped growing. Is this reason for concern? I also am having difficulty staying asleep more than 3-4 hours a night, and am having difficulty losing weight, even though I exercise 5 days a week ( treadmill 35 minutes at 3.0 miles an hour,plus 30 minutes of calisthenics each weekday). I eat about 1200 calories daily, according to my fitness pal. I don t know if these symptoms are related.
