Getting hung over easier as of late. I am 33.

I'm not sure if maybe it's me, but it seems like anymore i get hung over rather easy. I use to be able to drink no problem and never got hung over. However the other day I drank 1/3 a bottle of jack and 2 beers and I felt like hell the next day and pretty much just slept all day. Just a month ago i could have done this np but then i decided to cut back on the booze so i havent drank all month.I'm 33, does anyone else feel like they started not being able to drink like they use to?
