"took a single paxil pill and felt immediately sick within two hours or taking it. this &quot;sick&quot; feeling lasted for a solid week. i thought that i probably just got the flu at the same time i started taking paxil, so i tried it again. nope, still made me feel sick. i didn&#039;t think it was possible to get every single common side effect listed from taking one pill, but i guess i was wrong."
