It has been getting better since I started getting regular blood draws since last July. For me it's the fact that I can very distinctly feel the needle in my vein that makes me feel sick. The longer it's in the worse I get. And it's a whole lot better when I don't have to fast beforehand. On Tuesday I had my semiannual STD check, and that went pretty smoothly - relatively. I still hate it, but I'm getting better at just soldiering through it.
