I am taking what my doctor calls the kid's dose of 5 mg/3x a day. It has done wonders for my narcolepsy. I used to yawn non-stop, all day long and my attention span was very, very limited. I can now read dry, technical documents once and get the meaning instantly, instead of having to re-read multiple times. I have no trouble staying awake during the day. I can also listen to music and read at the same time which is something I've never been able to do before. I used to have chronic neck and back painóthey're gone now. I actually have energy to do physical activity, whereas before I would have to guilt myself into doing any physical work. For me this medication has been nothing short of miraculous.
