Make sure you have a health care provider who knows how to treat HIV. 

Begin treatment promptly once your doctor tells you to. 

Always keep your appointments. 

Follow your doctor's instructions.

If your doctor prescribes medicine for you, take the medicine just the way he or she tells you to. 

If you get sick from your medicine, go to your doctor for advice; don’t make changes to your medicine on your own or because of advice from friends. 

Practice safe sex to reduce your risk of getting a sexually transmitted disease (STD) or another strain of HIV. 

Eat healthy foods. This will help keep you strong, keep your energy and weight up, and help your body protect itself.

Exercise regularly. 

Get enough sleep and rest. 

Take time to relax. 

Many people find that meditation or prayer, along with exercise and rest, help them cope with the stress of having HIV or AIDS.
