Has anyone taken any medications specifically for anxiety?

I started a new medication, BuSpar (buspirone).
I'm just curious, my first time taking it was absolutely awful. It made me get serious head rush and I felt dizzy. Once that passed, I felt a horrible headache and I couldn't enjoy anything.

I've read some reviews on it, and I feel like it might be a temporary thing, if I can just last a week, I might be okay.
