Hello. : Hello. This needs to be comprehensively worked up if it not been yet. Depending on the results of this, your doctor may or may not send you for a consultation with a sleep specialist and for a polysomnogram (formal sleep study).

Sleep study: This is a problem , many options , getting a sleep study may really help, I would also suggest a urine organic acid test might be quite helpful. I would definately examine you environment for toxins or exposures that might contribute or cause . I would say a good general medical exam would be a good start
