Narcolepsy
"Was diagnosed with narcolepsy 30 years ago at age of 40 years old.  For the last 10 years have been on Adderall ( 2 x 20 mg at 8am, 2x 20 mg  and 2x 20mg at 1 pm.) &amp; Ritalin ( 2 x 10 mg at 9am, 12pm &amp;2pm) Reason  for Ritalin was to augment the Adderall &quot;peak and fall off&quot;.  I had tried Provigil when it first came on the but it didn&#039;t work,  Now at 70 yrs old it seemed that I had developed a tolerance Adderall.  After a lengthy discussion with health care provider, I agreed to give Provigil another try ( 200 mg once daily).  At next doctor&#039;s appointment, I complained of the &quot;afternoon fall off&quot; and the dose was changed to 200mg twice daily ( morning and early afternoon),  Issue solved and Provigil is working GREAT!!!"
