Brain fog after drinking

Hey everyone, I am generally “California sober”, but every once in a while for holidays or weddings I have a drink or two. I generally have between 5-10 drinks the entire year. This weekend, I went to a wedding in NOLA and had 2-3 drinks over the course of 24 hours. This was never enough to even get drunk or feel more than a tiny bit buzzed, but 48 hours late and I am still feeling completely wrecked. I am a teacher, my brain is on about 10% capacity and I can hardly form sentences let alone teach my students. Does anyone else get like this? I think I may just have to completely cut alcohol altogether. Is there anything that helps you when this happens? I’ve been drinking coffee and tons of water and have gotten a good amount of sleep.
