    Four simple ways to stay positive. Trying to stay positive, both in good times and bad, is a great way to improve your quality of life. Try these four methods on a daily basis.

    Don't think a lot about negativity.

    Of course, staying positive 24 hours a day, seven days a week is a bit difficult. Letting things get to you is normal, and it's actually healthy to cry or express frustrations once in a while.

    It's when those negative moments control your life that your emotional balance is at risk. {#blank#}1{#/blank#} However, don't give that sadness another second in your day.

    {#blank#}2{#/blank#}What you put into your body directly affects how you feel on the outside. Fill yourself with good, healthy foods like fruits and vegetables and limit snacking. Exercise is equally of great importance. Take a few days out of your week for at least a half an hour of activity, and try to stick to a routine. {#blank#}3{#/blank#}

    Be kind to others.

    {#blank#}4{#/blank#} Making someone's day a bit brighter not only puts a smile on his or her face, but also yours as well. Remember to smile and treat each person with pity and respect. Good deeds are contagious （传染的）, and your positive attitude may spread among others.

    Take it one day at a time.

    Being positive isn't an instant thing. It's a steady effort that we follow every hour of every day. {#blank#}5{#/blank#} Instead, focus on living in the moment and doing what you can to make each moment better.

A. Eat healthy and stay fit.

B. Take your lunch breaks outside.

C. Don't worry about what the future may bring.

D. Gratefulness helps you appreciate life in bad times.

E. Good feelings come from acts of kindness and selflessness.

F. Take a few minutes to feel sad and accept what happened.

G. Even going outside for a walk and enjoying the sunshine improves your mood.

    A daily multivitamin may give your well－being an extra benefit, but if you've ever swallowed one and felt sick right after, you know it's hardly a pleasant experience.{#blank#}1{#/blank#}

    You're taking vitamins on an empty stomach.

    Vitamins that are more acid in nature, like vitamin C, may cause nausea(恶心)if they're consumed on an empty stomach. Vitamins A, D, E and K, unlike some others, may be better absorbed when not taken with food.

    Multivitamins that contain a lot of iron or iron supplements themselves can cause nausea. This is especially true if you're taking them outside of a meal. Iron is interesting in that it's best absorbed on an empty stomach, but it's hardest to take on an empty stomach because of the nausea. {#blank#}4{#/blank#} It might decrease the absorption a little bit but it's better than nothing.

    Allergic reaction side effects.

    Since multivitamins contain so many vitamins and minerals, allergic reactions are certainly possible .Mild allergic reactions can include itchiness(痒) and a few hives(荨麻疹). {#blank#}5{#/blank#} Should you experience more advanced signs of an allergic reaction, such as trouble breathing, chest pain, widespread hives or a swollen facial region, visit the closest emergency room immediately.

B. Below are a few reasons why multivitamins may be making you ill.
