Yes, best advice is *Don't.*

But if you must, do this: Go to your physician. Tell her (or him) what the situation is. At this point, you will have 2 options:

1. Do what she says. (i.e., stay out of the plane)
2. Get some drug regimen that might, just might, save your ears. And, I don't know just how to say this...um...but it all depends on how familiar she is with your personal situation. The more so, the better the alternatives that may be offered. I guess what I'm trying to say, is, is she going to be afraid of being sued for malpractice if you suffer a ruptured eardrum, or if this happens, is she going to rag your butt unmercifully in hopes of returning you to sanity and then treat you so you anyway so as to try to prevent any permanent hearing loss if worse comes to worst? (and, yeah, I know, worst isn't correct here, but it is what we use in the South).

I guess what I'm trying to say here, is that in regards to this question, as well as many other related ones, is that if you go outside the typical man-in-the-street envelope, you really, really, need to develop a close and trusting relationship with your physician.
