"modafinil is quite useful and i have not experienced habit forming properties; this was a problem with all other adhd medications i have been prescribed over the past 10 years. although i also tried strattera for three months prior to my starting provigil.  my only issue is that so far i have only been able to receive 200mg which only helps me until afternoon.  i am in need of a large enough prescription so i can have an afternoon dose.  hopefully somehow my insurance can become convinced that this is necessary for my health."
