Excessive daytime sleepiness can make it difficult to stay awake and maintain normal daily activities. Modafinil 200mg (https://www.alldayawake.com/product/modafinil-200mg/) is a prescription medicine used to promote wakefulness in adults with certain sleep-wake disorders, including narcolepsy, shift work disorder, and excessive sleepiness associated with obstructive sleep apnea.
Modafinil works through brain pathways involved in wakefulness and alertness. The way it affects each person can vary, and it is not intended simply as a general solution for tiredness. Common side effects may include headache, nausea, nervousness, dizziness, or difficulty sleeping.
