Most people consume one form of caffeine or another on a daily basis. So what’s the big deal? Caffeine is a stimulating substance that can negatively impact your body. Excessive caffeine intake can cause symptoms similar to those found in anxiety disorders like insomnia, irritability, restlessness, and nervousness. According to the Mayo Clinic, heavy caffeine use is defined as 500 to 600 mg per day. If you are someone who drinks a coffee in the morning, a soda with lunch, and sweet tea at dinner, you may be in the heavy use category.
