It turns out I misunderstood my ENT office's instructions about when to stop taking my meds. I was thinking stopping at midnight on Friday meant nothing after 12 am today. But, they called with a reminder to stop all foods and meds on the list by midnight tonight. That feels much more doable. I'll take my Saturday morning meds right before midnight tonight. That just leaves Sunday since my test is Monday morning. I'm still a little anxious, but much less than I was before about having to stop my meds for a bit before my dizziness test.
