Yup: Seasick both on the surface and underwater. Light surge, but basically calm seas in the most calm of bays. Dehydration, lack of sleep, lack of taking care of myself is the explanation. Struggled through the swim, the Confined Water exercises, and the Open Water exercises, always a step behind.
Second day was better: Wasn't ill at least. Classroom work. My first prescribed teaching presentation went well. My theory tests are still not up to snuff.
Ah well, it is a learning experience, right?
