Michael needed to cram for a series of comprehensive exams,so he asked a friend for several "white cross" tablets, a type of amphetamine, to help him stay awake so he could study without sleeping for three days. Michael was able to stay awake, but he most likely would risk:

A) lapsing into a coma after two days of taking the pills.
B) becoming drowsy and unable to concentrate on his studies.
C) ―crashing‖ and experiencing withdrawal symptoms of extreme fatigue and depression when he stopped taking the pills.
D) hypnagogic hallucinations.
