Not I. But it depends what you are trying to do. Some advise that you should imagine you don't hold any OCZ shares and then imagine how many you would buy at the current price; this should be how many you are holding. It's hard to expel the emotion when you are holding and "frozen".
This thing is a little like a call option...you stand to lose everything or perhaps triple your money or something inbetween depending on what happens next. How much money would you risk on a call option?
