The antibiotics might be causing some discomfort, but from what you're saying he was waking up in the middle of the night anyway, wasn't he?
TBH I wouldn't worry about the 4hr mark at night at all, the point about a 4hr EASY is to make sure you LO is getting enough during the day, if he is then he should be able to go at least 8/9hrs without anything at night (hopefull sleeping

).
I think you need to make a decision about one feed to cut out and just go for it. I would suggest you feed your LO when he wakes up first time just so YOU are absolutely sure he is well fed - exactly to cover for those cases when you are not sure about one of the day feeds, or like last night, the last feed. Just see it as a top up rather than an extra feed he needs.
So let's say, like last night he falls asleep by 8pm, if he wakes up at 11pm do feed him. You know then that he can go til 4/5am safely without needing anything. If he does wake up between those times you can then do the PU/PD or give water, but just make sure he's falling asleep independently.
Again, this is just a suggestion, the main thing is that you decide what your plan will be and stick with it.
On the point about giving a bottle of EBM at night: some people don't see any difference, I found that with mine it worked well to give the last feed on a bottle - I think because they're sleepy they don't work as hard on the breast but since they can't stop the flow of the bottle they end up taking a better feed. (It also worked for my own head to see the amount they were taking - made me really realise they didn't need anymore 4 hours later).
