I’ve been wondering why some people continue to feel sleepy during the day even after getting what seems like enough sleep at night. I recently learned that sleep quality matters just as much as the number of hours spent sleeping. Conditions such as narcolepsy and sleep apnea can interfere with restful sleep and contribute to daytime tiredness. I also came across information about Modaxl 200 mg modafinil tablets, which are prescribed for certain sleep-related conditions. However, I understand that persistent sleepiness should be evaluated by a healthcare professional before considering any medication. These sleep health and wellness resources also provide useful information about sleep patterns and daytime alertness. Has anyone explored the possible causes of persistent daytime sleepiness with a sleep specialist?
