I would add one more thing. Exit your long put/call the Friday before expiration. Whether it is profitable or not, you will keep some time value. In other words, suppose your option is 10 points ITM. You may be able to sell this option for 12 (using limit orders and keeping an eye on the bid/ask spread). This is better than holding the thing for another week and possibly losing the entire profit and your premium. Now, suppose you have a loser. By exiting early, you will get some money back assuming the option isn't DOTM. Otherwise, it expires worthless and you lose the entire premium.
