Dose may be low: The dose maybe somewhat low. Comes in 50s, 150s and 250 in the us. The half-life is 12 to 15 hours. I do not generally encounter tolerance developing to this medication. The only exception to that rule might be someone with idiopathic central nervous system hypersomnolence. Best wishes and i hope that this does a good job working on your hypersomnolence. Take care.
