HELP 😞

My son had his 2 month shots yesterday and I mean he's usually a calm good baby but he's been sleeping like no other and he's a lot more winey when he actually does wake up to eat. I've been having to wake him up to eat. And then he goes fast to sleep right when he's done. Is this normal? I'm giving him Tylenol as directed but I don't want to over do it?? Ftm! Help please :/
