I had to do that with everything. We had to block the TV, the Internet, the PCs, the Xbox, and basically anything that could provide entertainment because my son would get up after we went to bed and stay up all night long. It was a frustrating phase for sure.
Not OP, but for me, I basically blocked staying up too late on a school night, and excessive time in game (not PlayStation though)
