1 bottle a night??

I am exclusively breast feeding my son but when he is fussy and hungry in the middle of the night, he has a hard time latching and with me being tired, it gets frustrating. It sometimes takes him 30 mins to latch and by that time I'm exhausted. 
He then feeds for almost an hour because the boob is comforting for him. 
I had 2 glasses of wine one night and bottle fed him breast milk from the freezer and it was a breeze in the middle of the night. He immediately took it and ate in 10 minutes and went right to bed after being burped.
I am considering feeding him from a bottle once a night so I can get some rest and we don't have to try latching for 30 minutes. Is this okay?
