I take buspirone 5mg twice a day (10mg) and within the last month or so (3 month mark) I've been getting waves of dizziness. They are short little bursts of dizziness though and it's usually when I'm laying down or sitting. It's like that jerky feeling you get when you're almost asleep and you feel like your falling. It lasts maybe a second but it hits me randomly all day.

I don't really get headaches but the back of my neck and shoulders hurt.
I'm not sure what to do and of course with anxiety I'm scared for the worse like a brain tumor or something.
