I'm just posting my recent experiences on here since I have been posting a lot recently due to being excited about getting my certification.
Anyways, I am in Grand Cayman right now and arrived Thursday to start the checkout dives on Friday. Early in the week I could tell I wasn't feeling too great so I opted not to go to the gym to left my body rest. The day we arrived here I didn't sleep much since we had to leave at 3:30am to get to the airport so I felt kinda blah.
Friday morning I woke up and felt really sick and I felt like I had a fever and flu like symptoms. I ended up getting some medicine very early and took it and then by the time they picked us up for the dives it was 11:30 and I felt okay. I also really had no appetite all day.
I talked to the instructor who organized the trip and he said if I felt up to it to give the first dive a try as it was 20 feet max, and see how I felt. If I felt bad any time during the dives to just let the instructor know and to call it off. So I ended up doing the 3 dives and felt okay during them all although I kind of had a headache but it wasn't enough to bother me or keep me out of it.
When I got home it started to hit me more though. I got home around 5:30pm and just started to gradually feel worse and worse. Eventually I ended up falling asleep but again I didn't eat much as I didn't have much appetite.
I ended up tossing and turning like all night and I could clearly tell I had a fever. I had to call off the next dives and ended up going to see a health clinic here and they thought I had some kind of flu. They put me on tamiflu and a few other medicines and my ears also were clogged with wax to they cleared them and gave me ear drops. The doc said to not bother with anymore diving while I'm here as it's risky.
So even though I'm here until Tuesday I unfortunately won't be able to complete the last dive. I really wished I could do it with the group because they did 5 AOW dives afterwards that I would have 100% done as I felt super comfortable after just the first dive. Instead of having 9 or 10 dives under my belt I only have the couple training dives.
I'm either going to come back with another group trip here so I can do the 4th dive and then the next 5 with the group, or I may just take the referral and do the final dive in the Keys or something. I really like being with the group though and after just the first day you could feel the comradre and accomplishment everyone felt.
But oh well, health is more important than diving in the grand scheme of things, it just really sucks that the only reason I planned this trip and came here is something that couldn't be accomplished.
Like the others, I agree that it is better not to dive when you are not feeling well. Years ago my husband ruptured an eardrum in Bonaire. He had a cold but was okay during the dive but got a reverse block while surfacing. He went back down and stayed down for quite awhile trying to clear it but was unable to do so. Eventually he had to surface and when he came out of the water, blood was flowing out of his ear. That was the end of diving for that trip and he was sick the entire vacation.
But there is something else that I want to mention. Over the years it has happened many times that one or the other of us (or both!) have gotten head colds and ear/sinus infections that have affected our vacations and diving. We have concluded that it is primarily because we are run down and sleep-deprived when arriving at the vacation destination and that flying and diving adds other congesting complications.
We've tried getting ready for the trip earlier so that we won't be so run down, but somehow that never happens, our jobs keep dumping demands on us to the last second. Maybe when we retire it will finally be easier. What we do now, and it has been working for us for several years, is to plan some rest and relaxation at the start of the trip before we go diving.
We used to rush right out to dive or get on the liveaboard as soon as we arrived, even though we were really exhausted. And we would do a lot of diving, 4-5 dives per day when we could get them, even if we didn't feel good. Now we give ourselves some time to get relaxed and healthy before we go diving and we just take things easier. It means that we now take fewer, longer dive trips but we have a chance to stay healthy, and enjoy ourselves and our diving.
We have also found that using a netti-pot to give ourselves nasal and sinus rinses, before, during and after the trip, along with taking anti-histamines and decongestants, helps to keep our heads clear and prevent colds - but don't take a new medication right before you go diving - make sure to use something that you know that you tolerate well; we like the Allegra-D 12 Hour product.
Our system may just work for us, but I am passing it on because I know the disappointment of taking a long-awaited vacation to a beautiful dive destination and then getting sick and being unable to dive.
Enjoy your time on GC, there is lots to see and do topside on that beautiful island!
