Narcolepsy
"About 6 years ago I was diagnosed with narcolepsy and sleep apnea. I started taking Provigill 100mg once per day. Then 200 mg once per day. Then my Doctor tried me on Concerta, it had a quick peak of energy but it didn&#039;t last at all; plus since it is a controlled substance it was harder to get. We had to go to the Doctor in person every month to get a prescription unlike other medicines that allowed pharmacy refills. My Doctor switched me back to Provigil 200 mg twice a day. This amount actually worked but most insurance plans only allow 1 200mg per day. After Nuvigil came out my Doctor switched me due to insurance company wanting to save money. Nuvigil 350 mg 1 per day does not work for me. I have a low 4hrs after I took it. "
