The insurance companies are getting ridiculous!!! Nuvigil works very well for me but my current insurance has denied it twice stating that because I dont have narcolepsy, sleep apnea or wear an apparatus at night they wont cover it...... I even sent research on it, which is now being called primary hypersomnolence but they denied it again...... They did approve Ritalin which raises my already high blood pressure but they didn't care to hear about that....
