I am freaking out here. I took a pain pill at work and it is making me react like I am on meth. I am shaking and my heart is beating like crazy. I am having a full blown panic attack and I am at work. I should have known better because although these pills usually make people tired, they have the reverse effect on me. It is like I am still on drugs or something, although I have been clean almost three years. I don't like this feeling.
