Hangover Question

Hello, I will start off by saying I have never before prior to this even had as much as a sip of alcohol. I recently acquired a bottle of Pink Whitney (750ML) I believe and drank some this weekend. My friend told me I’d have a bad hangover but both mornings I didn’t feel much different. The exact amount I drank I am unsure of but I can confidently say I drank about a little more than 2/3 of the bottle combined. Am I just really lucky or did my definition of a hangover come from shows? I assumed I’d be wanting to vomit and such but I haven’t even felt sick.

Secondary question, is that a lot for someone who just started drinking? I didn’t feel much so I kept drinking the first night and got really drunk, body felt fuzzy and could barely walk. But the second night I drank a little more than that I think and could still function.
