obstructive sleep apnea/hypopnea syndrome
"Provigil has given me my life back!  I have been on 200mg twice a day and the results are great!  When I quit teaching and went on my husband's insurance, the insurance company refused to pay for two times a day, so my doctor put me on Nuvigil.  I was on it for 6 weeks and I was always tired.  I am moving back to Provigil. "
