I wasn't aware that nittel had specific things that were supposed to be discussed while you were batteling, is there a siman I missed in Shulchun Aruch that discusses it?
Did you really finish the entire Shulchan Aruch that you are asking if you missed that Siman?
Besides, if it were in Shulchan Aruch it wouldn't be allowed to be discussed on Nitel. Nor would he have given the options if it was clear in Shulchan Aruch......
There are a lot of different reasons for the word "nittel" - but I never heard it has anything to do with Battallah.....
