Fatigue after tooth extraction

I’m about 5 days post wisdom teeth extraction and I just feel very tired & weak. I feel kind of short of breath sometimes and my arms are tired when I try to lift anything. I didn’t get IV Sedation I only got laughing gas. I’m not really in any pain anymore my right side is just a little sore. Did anyone else feel like this after? Maybe it’s because I haven’t been able to have real food idk. Only been eating ice cream, ramen noodles, and mashed potato’s.
