Buy Modafinil Online is a wakefulness drug that can increase alertness and focus. It works by blocking the reuptake of certain neurotransmitters in the brain, specifically dopamine, epinephrine and norepinephrine. It can cause a variety of side effects, from dizziness and nausea to headaches and depression. Although it has been used to treat narcolepsy, people are also taking it off-label as a cognitive enhancer. There is no scientific consensus on its effectiveness for this purpose. While it may boost alertness in people who are sleep-deprived, other studies indicate that it does not improve learning or memory for basic tasks. Moreover, it may even impair creativity and reasoning skills.
