Does coffee cause anxiety? Not for everyone...

I've read conflicting opinions on whether coffee causes anxiety. Nevertheless, from personal and professional experience, I have decided on an opinion shared by others:

If you're a highly anxious, high-strung person, having a stressful day in hopes that coffee will make you feel better or not used to the amount of coffee you plan on drinking, then DON'T DRINK COFFEE.

Some say coffee causes you to become anxious, so avoid it all together. I believed this growing up, because I remember one time my mom was given regular coffee - she strictly stuck to decaf - and her heart raced so fast I thought she might have a panic attack. It is only partly true; avoid coffee all together if you fall under the aforementioned individuals. My mom and I are both naturally anxious people, so it makes some sense why she reacted the way she did to regular coffee.

During her college years and for the past few years, however, my mom is much more relaxed and calm, thoroughly capable of enjoying a Tall (16 oz. or "Grande," according to Starbucks) Americano made with regular espresso and Monin sugar-free almond syrup without any adverse effects. She now gets the positive effects from caffeine that most Americans receive daily: higher attentiveness, heightened mood and more.

My advice to reap the benefits from coffee consumption is to learn your limit. My daily limit is no more than 1-12 oz. brewed coffee or specialty espresso drink. Any more than that and I feel jittery and sick to my stomach.
