Suggest Alternative Medication For Provigil

Why do drug representatives give all 3 of my doctors samples of provigil to give to their patients who can t get out of bed because of OSA, and many other sleep problems to see if the drug works for them. Then when we find out provigil does work my doctor keeps getting denied his P A even when the drug is on their part D formulary. If they don t want to let patients who need it take it then stop giving it to our doctors to give out as samples! It s the only medicine that enables me not to sleep all day!!!!
