People with sleep disorders including narcolepsy, obstructive sleep apnea, or shift work sleep disorder are known to benefit from armodafinil's ability to increase wakefulness and alertness. It can enhance focus, provide more mental clarity during the day, and lessen excessive afternoon drowsiness. Many claim to be more productive and less tired without experiencing excessive stimulation. For some users, it is less likely to cause jitteriness than typical stimulants. Armodafinil-containing drugs, such as Waklert 150, are usually taken under medical supervision to safely control symptoms rather than as a cure, and individual results may differ.
