I got to Rogers Rock on Friday. I expected to dive & snorkel Friday, classes Sat and Sunday with a catered dinner Saturday night and some dives Monday. I got my tent set up and that was about all. That afternoon I couldn’t cool down, was sweating profusely and feeling light headed and a bit nauseated. I laid down for a while then had something to eat with the group then went to bed - or tried to. I was up all night with really bad chills alternating with being overheated with uncontrollable sweating, continuous nausea, and weakness. When I got up on Saturday morning I knew I was not going to be able to dive let alone take Nav, Dark, and Deep cert dives. Right now (Sunday mid-morning) I still feel pretty much the same. I had to get out of bed for a while - been there since I got home about noon Saturday. I’ll get something bland to eat then back to bed. Don’t know what this is but it feels like malaria. If I don’t start feeling better by tomorrow morning I’m off to the Dr. The sad part is I never even got into the water.
