#18 - Almost Got to Keep This Unit

When I donate blood, I am still struggling to find the right balance between not enough pre-hydration, which in the past meant my veins would be too flat to puncture, and too much pre-hydration, which has meant that I had to pee really bad. This time I was almost too close to flat veins, but they found one they could work with at the last minute. One more to go.
