If you feel extremely tired all day with heavy legs but when you try to sleep you have insomnia and can’t fall asleep... supplement vitamin D (10,000-50,000IU once weekly)
In this case report study, the patient had hypersomnia (excessive sleepiness during the day) and a vitamin D level of 5.9 ng/mL which is very low.

At a later follow-up, the patient reported resolution of thigh pain, headaches and hypersomnia, with a significant improvement in low back pain.
Vitamin D level was normal at 39 ng/mL at this point
