I find that the following method is a decent substitute.
I now completely forgot who first stated this one, though I think it was allen (if I'm wrong, will the real person please say so).
Slowly close your eyes and roll your eyes upward, and pretend you're staring through the top of your skull at the ceiling. Breath calmly, and after about 15 seconds, you should emerge in a state similar to the one the tangerine technique puts you in.
Works for me, anyway.
