Actually I would recommend both but if you are planning to take the Benadryl after the surgery make sure your surgeon is aware as they may want to go ahead and give you a prescription strength medication to prevent this from occuring and also so that you do not take a chance in any drug interactions with any pain medications or other prescription medications they may send you home with. And yes the bath would still help greatly and do let them know how much trouble you do have with sleeping and resting after surgery as the more they are aware of your symptoms the better they can prescribe medication to help you with this. And it is not a problem you needing more information, that is why I am here is to be of help to you.
