Anxiety
"I have social anxiety &amp; knew I&#039;d literally fail out of grad school if I did not do something about my immense fear of public speaking (when my Social Anxiety is at its worst). I&#039;d have a shaky voice, dry mouth, nausea, my heart would race and I would be physically shaking. Knowing those physical side effects would happen just made me more nervous and make it even worse.  I take one of these an hour before my presentations now (and only when I have a presentation, like every few weeks, it&#039;s not a daily thing!) &amp; it *definitely* lowers the physical effects so I can get through it, though I still get (way less) nervous. I only get a slight shaky voice, but my heart does not race, no dry mouth, nausea &amp; I don&#039;t shake. It was honestly a life saver for me."
