Hi - my name is XXXXX XXXXX I'm a Criminal Law litigation attorney. Thanks for your question.
Whether it is worth attempting to have the protective order lifted really depends on how much of an impact it will have on your life. If the order will not really affect your day to day activities, then it may not be worth it.
Also, courts are VERY cautious in regard to lifting protective orders. There must be a showing that there's no longer a threat or chance of harm, etc. before a court will consider lifting the order. Thus, it may be difficult to overcome the protective order, which could also be a good reason not to spend money fighting it.
However, if the protective order is going to make your change your daily routines, etc., then it may be worth challenging the order and try to prove that there's no danger or threat of harm and that the order should be lifted.
The problem is that these types of claims are based on one's word against the other, and the court is not likely to lift the order if the other personn says that he/she believes there's a chance that harm will occur if the protective order is lifted.
