For Drowsiness "I took Vivarin almost every day for over 15 years, close to 21 years. I didn't realize that I was suffering from hypothyroidism. All I knew was that I had the normal energy that I was missing. I finally started taking 1/2 tablet because a whole tablet was causing my heart to flutter. Soon I was taking 1/4 of a tablet, and finally I had to quit taking them. After all those years, I am suffering with a damaged heart, heart arrhythmia (AFIB), tachycardia, and congestive heart failure. I have no blockages in my arteries, just a damaged heart and the baggage."
