Has Andy tried chewing gum before a dive? I tried that the last few times I went out, and it made a significant difference in my clearing ability. I just start chewing about an hour before the first dive, and spit it out just before I'm ready to splash in.

Andy has tried every remedy we can think of. Steve Parker told me while we were at ABWA in February about an ENT in Birmingham that works with divers. Andy's problem seems to be smaller than normal eustean tubes. This doctor works with dive patients and there are exercises you can do to remedy this. We have just got to find some time when Andy isn't tied up with school to get him up there and let this doctor work with him.
