"having been told over 12 yrs ago that i had adhd i have tried several medicines. the main one i used is adderall 30mg twice a day. this has proven very effective. having tried both provigil and nuvigil both i believe nuvigil to be the better of the two. none of the traditional side effects of speed and nuvigil is very clean. so much so and i know this sounds goofy but you don&#039;t even realize it&#039;s working until you shake your head an realize how focused, alert and clear thinking you have been."
