My hangover lasted 4 days, is it normal and has it happened to anyone else?

Some background, I’m 33m and haven’t drunk in about a year. In addition I’ve lost a lot of weight and am kind of skinny now.

So I decided to go out last week on a Friday and had about 5 beers. I didn’t even get that drunk, just really tipsy. The next night I could feel I wasn’t fully recovered from the first but I felt good enough, so I went out again. That night I may have had 6 or 7 beers.

I didn’t even get a bad hangover the next day, just a slight headache and honestly I think I was still a bit tipsy for half the day. However I felt groggy, kind of nauseous and had head fog like I couldn’t think clearly. That took 4.5 days to go away before I felt normal again.

I will definitely drink less in the future, I will try 2 beers max when I go out and see how that works. I’m just wondering if anyone else has had symptoms last that long after drinking?
