Every time I tip my head back in an asana, I feel like I'm going to toss my cookies. I seem to be averse to inversions. I'm told that it will subside with regular practice, but it hasn't yet. Admittedly, my asana is anything but regular. Does anyone else have this problem? All I have to do is think about tipping my head back and I get woozy. I used to have tinnitus, and suspect this may contribute. I'd be curious to hear if anyone with tinnitus has this problem, and if you've found any solutions.
