Maybe I am off a month but 18 months ago was when the stock took off and broke a penny....It traded between a cent  to five for over a month. 
I am not trying to ridicule you, I just think you invested on the second knife fall which means it was less than 18 months ago. Then again its your money, just seemed like you lost profit and not your actual investment but I am not seeing your broker account. If you did take that big of a hit you need some rules man.
I can say I am over 98% down from profit I didn't take.
