Alternatives: As with insomnia (see benzodiazepine hypnotics, above), it's important to identify the cause of excessive daytime sleepiness. Other medications you're taking — whether prescription or over the counter — could be responsible. Drugs with sedating effects, for example, are among the most common causes of excessive daytime sleepiness. (These include alpha- and beta-blockers, anti-diarrheal agents, antihistamines, antipsychotics, antispasmodics, cough suppressants, epilepsy drugs, skeletal muscle relaxants, Parkinson's drugs and some antidepressant medications.)
Alternatives: If you're among the millions of older Americans who haven't been diagnosed with heart disease but are taking these drugs to lower your slightly elevated cholesterol, ask your doctor or other health care provider about making changes to your diet and getting regular exercise instead of using statins. You also might try lowering your blood levels of homocysteine — which is linked to high cholesterol — by taking a combination of sublingual (under-the-tongue) vitamin B12 (1,000 mcg daily), folic acid (800 mcg daily) and vitamin B6 (200 mg daily).
