Be Happy
This inyan is very complicated and its best to ask a Rav because there are so many factors that come in to play with Brachos like Shinuy Makom, Hefsek, Shiur for Bracha Achrona, if the food/drink was eaten within the zman of Bracha Achrona like Kdei Shtiyas Reviis or Kdei Achilas Pras, Sheilos of Brachos Levatalos and Sheino Tzrichos.
PLEASE ASK YOUR RAV!
