Took it for about year or so. Nothing bad to say. For me it didn't seem to be very helpful. Then as usual, it seem to have no effect at all.
NOT to discourage though! Many say it works well for them!
I personally develope a tolerance extremely quickly to EVERY medication I have taken so far.

Wake is very expensive where 'I live - like a monthly salary - it is supposed to be THE best drug for narcolepsy so good luck!
