@sparrow1210, I think the retreat will be great fun, definitely go! And I think the breathing should be ok if you have all the information going in - don't do it as intensely as you can, don't push the air to create head pressure. If you notice anything at all going on with the ears then take it easy. But millions of people are doing it without the permanent side effect, we just got very unlucky here.
@MrC6688, oh man, sorry to hear all that. You must have it much worse than me then, I can easily hear TV or music over it. Only thing I can't really do like that is listen to something like a podcast with noise-cancelling headphones. Usually it doesn't disturb me when I'm sleeping, unless I've done a lot of inversions that day in which case it'll be louder and I'll need some sounds on. I find usually it's less noticeable in the morning when I wake up (not always but usually). Sometimes it starts as more of just a hissing and the high tone comes in later after a coffee or exercise or just being awake longer. I might just get some of that Saraswati Churna and try it out, see if I can repeat the results you had. Will update.
