During the last 150m of the workout, everything took on a blue tinge. After I got out of the pool, I couldn't walk straight...my legs were were wobbly and I kept feeling like I was going to fall over. I had to lean over the water fountain for a minute or so and take it real easy walking back into the locker room. I peed, rinsed, spent a few minutes in the dry sauna, showered, and felt okay by the time I walked out of the gym. But that was not a feeling I enjoyed.
