"There are two questions associated with this case." "Insomnia-Fatigue Case 2." A regular patron of the grocery store pharmacy comes to pick up his monthly refill for temazepam (Restoril), which is a long-acting benzodiazepine. He also wants to ring out a 4-pack of Corona Light and 4 sugar-free Red Bulls. He seems out of it - you ask him for his birthday multiple times and each time he gives you his address Question 1 of 2: Which of the following causes of daytime sleepiness can be treated with self-care measures like drinking a Red Bull?

A. Short-term, transient insomnia due to lifestyle changes: This type of insomnia is often caused by stress, travel, or temporary schedule disruptions. Mild interventions such as caffeine consumption, limiting naps, and improving sleep hygiene can provide symptom relief, making it appropriate for self-care measures like drinking a Red Bull. B. Narcolepsy: Narcolepsy is a chronic neurological disorder characterized by excessive daytime sleepiness, cataplexy, and sleep paralysis. It requires prescription management and behavioral interventions, so self-care measures alone are insufficient. C. Restless leg syndrome: Restless leg syndrome causes uncomfortable sensations in the legs and an urge to move them, often interfering with sleep. Treatment often includes pharmacologic therapy and lifestyle modifications; caffeine may actually worsen symptoms. D. Obstructive sleep apnea: Obstructive sleep apnea involves repeated airway obstruction during sleep, leading to excessive daytime sleepiness. Management typically requires CPAP therapy, weight management, or surgery, making self-care measures like caffeine inadequate.
