Buy Modalert 200, a popular modafinil medication, often starts working 30 to 60 minutes after consumption. Many users notice enhanced alertness, improved focus, and decreased fatigue as the medicine reaches peak levels in the bloodstream, which normally occurs 2 to 3 hours after taking it. Its effects can continue for 10 to 12 hours, making it very effective for shift workers or people who experience extreme daytime sleepiness. 

Because responses vary depending on metabolism, food intake, and overall health, it is advised to take Modalert on an empty stomach for a quicker onset and to follow medical advice for safe use.
