It's 2 a.m. and you can't sleep. Is it okay to take a nonprescription remedy? "They're not meant for the long term, but it may be okay for an occasional night of problems with sleep," says sleep expert Dr. Lawrence Epstein, an instructor in medicine at Harvard Medical School.

But which option should you reach for? Drugstore shelves are lined with a dizzying array of products promising a good night's sleep. They fall into two categories: nonprescription medications and dietary supplements.

Your sleeping cycle changes as you age, but there are ways to ensure you get a good night's rest.

Most men experience bouts of sleeplessness as they age. They have trouble going to sleep, wake up in the night, and then have trouble falling back to sleep.

Most of this has to do with normal aging, but don't think you need less sleep because you are older. "Research has shown that your sleep needs stay constant throughout adulthood," says Dr. Lawrence Epstein, associate physician with the Division of Sleep and Circadian Disorders at Harvard-affiliated Brigham and Women's Hospital. "Instead, it's your sleep patterns that change, and that is what can interfere with sleep quality."

To eat a healthier diet, you need to combine nutritional science, a jolt of common sense, and pure enjoyment. Most of us know that fresh salad, berries, and slowing down when eating are better for us than wolfing down energy bars and sweets. But how to make that leap from our current habits to healthier ones?

Here are six ways you can eat healthy, delicious meals, and really enjoy what you're eating.

Back pain is one of the top reasons that people begin to lose mobility in middle age. Pain can keep people from engaging in physical activity, making it more difficult for them to maintain a healthy weight and keep up their strength, stamina, and balance as they age. So treating and managing back pain that results from injuries or health problems is crucial for staying on the path of a healthy and active life.

Considering that most people spend roughly a third of their lives lying in bed, choosing the right mattress is essential for managing low back pain. It can make the difference in whether you can sleep at night and function the next day.

Of your five senses, which one are you most afraid of losing? If you're like most people, your answer is your ability to see. Because  our eyesight is so precious, it's no wonder that myths abound about your eye health, what can damage our eyes — , and what can protect them. Here, we debunk five common myths — and tell you how to truly keep your eyes healthy.

Myth: Doing eye exercises will delay the need for glasses.
Fact: Eye exercises will not improve or preserve vision, help your eye health, or reduce the need for glasses. Your vision depends on many factors, including the shape of your eyeball and the health of the eye tissues, neither of which can be significantly altered with eye exercises.

Ask the doctor

Q. I just can't lose weight. A friend says that my problem might be due to the types of bacteria that live in my gut. That sounds crazy to me, but is it true, and can I do something about it?

A. Ten years ago, I also would have thought your friend was crazy. Today, I'd say she could well be right. Here's why. We've known for a century that bacteria live in our intestines, but we've assumed that they did little to affect our health. We thought that they were just mooching off of us — taking advantage of the warmth and nutrients in our gut.

A new study raises questions about whether they're truly equivalent to the brand-name versions.

You've no doubt seen them in the grocery store — typically drab-looking packages on the bottom shelf containing lower-priced generic versions of popular brand-name products. Some shoppers look at them with skepticism: Are they really as good? Or does cheaper just mean lower quality?

Many people have the same questions about generic prescription medications, says Dr. Niteesh K. Choudhry, professor of medicine at Harvard Medical School and executive director of the Center for Healthcare Delivery Sciences at Brigham and Women's Hospital. Are generic drugs really the same quality, or is it better to spend more for the name-brand version?

Each one can have a different timetable. Find out in advance what you should expect, and then track your symptoms.

When your doctor prescribes a new medication, you may expect to start feeling the effects right away. But some drugs can take time to make a difference. "It depends on how quickly your body absorbs the medication, how your body distributes it, and how your body breaks down or metabolizes it," says Laura Carr, a pharmacist at Harvard-affiliated Massachusetts General Hospital.

Giving it time

Some medications start working on the first day. These include drugs that treat high blood pressure, like the beta blocker metoprolol (Toprol, Lopressor), which slows down the heart and reduces the force of its contractions; or H2 blockers such as famotidine (Pepcid) and ranitidine (Zantac), which treat heartburn by blocking the stomach's acid-secreting cells from making acid.

Most older adults take some kind of over-the-counter dietary supplement. But are these products right for everyone?

Over-the-counter dietary supplements are big business — more than 90,000 products generate about $30 billion every year in the United States. Older adults make up a big part of these sales, too. A survey of almost 3,500 adults ages 60 and older published Oct. 1, 2017, in The Journal of Nutrition found that 70% use a daily supplement (either a multivitamin or individual vitamin or mineral), 54% take one or two supplements, and 29% take four or more.

But are these pills good medicine, or a waste of money?
