Brain fog - Probiotics? What do i do?

I have been prescribed Fluconazole, Cyclopam (abd pain) and a probiotic for my fungal infection. I've never had Curd or Buttermilk in the entire 21 years of my life. After I took those pills, i've had my lunch (had basic rice, dal and curry). After 20-30 mins I suddenly started showing symptoms of : Dizziness, Light headedness, Lack of concentration. My mother was trying to ask "If i was okay? What was happening with me?" Such a simple question was also hard for me to process. I wanted to reply back but kept re-thinking what did she exactly ask. Also, the voice of my parents talking and the noises around sounded amplified. I kept touching my neck to see if i had any fever and was in a complete state of paranoia. Then I decided to sleep but had terrible nausea and an episode of diarrhoea but managed to sleep later. I woke up after 3.5 hours & completely felt okay. But how i felt before were all pointing towards brain fog. I just wanted to know is this possible? If yes, WHAT DO I DO?
