"Feeling dizzy" was actually a pun, lost in translation. The Japanese word noboseru mean both "feeling dizzy" and "feeling prideful". In that scene, Byakuya says he will earn his right to feel prideful again, while Kirinji did ask him if he felt dizzy.

Either way, I think at least a day or two passed between Kyoraku meeting with Ichigo's friends and the second invasion's beginning. Byakuya should feel much better now.
