I took a 5mg hydrocodone for my lower back. Then took a 25 mg hydroxyzine to help me fall asleep. This was around 12. I was still up around at 3:30 ish. So I decided to take 100mg to help me fall asleep. 30 minutes later I started feeling weird so I jumped up out of bed and it became a worse feeling. I felt horrible then woke up kneeling sorta. I'm worried that I had a seizure or just passed out. Had a intense head after waking up. Can this cause future seizures to randomly happen if it was one?
