When bacteria die, they can release something called lipopolysaccharides (LPS)—also known as lipoglycans and endotoxins—which are found in the outer membrane of Gram-negative bacteria, and elicit strong immune responses in animals. Sudden, concentrated antibiotic usage can trigger what is known as "die-off" when large amounts of these bacteria die all at once. This causes an acute increase in both circulating endotoxin and serotonin. The increased endotoxin, serotonin, and—possibly in your case—ammonia may have been what contributed to the "hazy" mental state.
After the bacteria are dead and gone, you return to the lower endotoxin and serotonin state from before they inhabited your intestines. Serotonin has an appetite suppression effect, and now that you a freer from bacteria which were creating inflammation with endotoxin and your serotonin is lower, your appetite has rebounded greater than before and you can expect an increase in metabolism and greater clarity of thought—especially if you maintain this state.
It will be useful to now keep your intestines clean by using particular food choices so that you both maintain a healthier state and prevent something nastier from moving in now that the competition is gone. Having milk in your diet and 1 tbsp of coconut oil a day might be a good start, as they both promote more reasonable bacteria populations in the gut.
