17 Sep 2011	I can't go a day without caffeine. It makes me wake up and stay away. The only thing bad is that you can't have it too late or else you'll never fall asleep —Posted by Anonymous Respond Display Name: Email: (Required) Notify me of new comments Email me monthly survey results Sending...

31 Jul 2011	I usually use excedrine because there is caffeine in it with the aspirin and acetaminophen rather than just caffeine. Or just a cup of coffee seems to help —Posted by Anonymous Respond Display Name: Email: (Required) Notify me of new comments Email me monthly survey results Sending... I agree to the Terms of Use
