Side effects may include dizziness, inability to use arms and legs, not to mention speech, properly, an incredible urge to eat the paneling off the wall, after everything ELSE of sustinence value has been consumed in your dwelling, and the willingness to, well, like Chicago asked in the song 25 or 6 to 4, "should I try and do some more?"
