Amphetamine / dextroamphetamine
"Prescribed for ADD and excessive daytime sleepiness. Very good at helping me focus when I need it. It also works TOO well for my fatigue, I went from feeling like a narcoleptic to having insomnia. I had to cut back on my prescribed dose because it was too much. I take only 5mg when I need it. Even though this medication will wake you up, you absolutely must manage your time and get some quality sleep, because most side effects come from lack of sleep. Be careful with this as it can be habit forming and addictive. The key is to eat well and sleep well when on this medication."
