m17 drank 4 straight beers and didn’t feel drunk, is this normal?

so I drank alcohol for the first time yesterday with my brother, I ate before the drink which was recommended and waited for 4 hours and I didn’t feel any signs being drunk, I just felt sleepy during that time. I don’t really understand, I’m skinny and 5’7. the weird thing is when I woke up I didn’t feel my body hurting and I didn’t vomit. I drank corona 5 percent alcohol
