i would buy puts not "naked" so to say. time decai from options is very strong, you loose money every day.
maybe a wide butterfly spread could help, or a risk/reversal...
...but in general my rule is: If i'm not comfortable with my trade anymore, i close it. Even better for you if you have profits.
Decisions such these should be made prior to initiating a trade (Plan The Trade And Trade The Plan). §8-)
