I went with the open water class to the Coral Gardens next to the Canyon. We had to do the CESA (Controlled Emergency Swimming Accent) with the students. Jack did one and I did the other two -- each a couple times. By the end of the dive my ears were feeling very abused. Had take away falafel for lunch, then hung out studying at Nesima. In the afternoon I went with the open water class on the boat to Napoleon Reef. During the dive I had major ear problems - well not major, but I was uncomfortable and it took a lot of time to equalize. It was kind of fun though since I got to lead the dive. Michael tagged along with the group (Elizabeth, his girlfriend, is one of the students) and at the end of the dive we had enough air left to let Jack take up the students and we went on a 20 minute fun dive. The fun dive was mostly fun because I didn't have to worry about anyone and we could move at a reasonable speed (actually we raced along - it just felt good to cover some ground). Back at Nesima I was just feeling very run down. I tried to have a beer but it just didn't appeal. Ended up having dinner and going to bed feeling very low.
