"i found out about 5 years ago i had a sleeping disorder. i would fall asleep driven seating at red lights and even at work. i never wanted to do anything but sleep. but now my dr. has me on methylphenidate er 24 hr 40mg. once a day and also ritilin 20mgs once a day. and now i can drive and work and not be scared to fall asleep. so now i can get on with my life and do things with my wife and sons and not want to sleep. it has changed my life for the best."
