You're fairly lucky you didn't experience any withdrawal symptoms. A lot of people experience flu like symptoms or these fun things called brain zaps. It's generally recommended that you tapper off your dose rather than just quitting cold turkey.

Just like the effects of Paxil slowly build, they also slowly wear off. Each day without it, as I understand it, causes your brain chemistry to slide ever closer to where it had been. Go back on Paxil again and the effects will again start to build.
