Yeah - to make it more irritating, if you use Embrace, the Faery will automatically go into Guard and use all her cooldowns. To manually control both the Faery's Embrace and her cooldowns, you will need to do...

Embrace > Steady > Physick

I have Embrace hotkeyed to alt+q, steady to alt+w, and Physick to alt+e. I hold alt and roll through q, w, and e every cycle I want to heal. This can be an enormous pain, though, and I sometimes wonder if it's worth it. Once your Whispering Dawn is on cooldown, you don't really have to worry about it for the next 59 seconds.
