I have Drew too, and he's been a pain in the you know what! I've just decided to keep him on my bench for now and see what happens. If I waive him, I know someone will pick him up immediately, but at the same time, no one wants to trade for him. They'll gladly take him for free, because he could blow up at any time. You can't get much in return. If you can stomach someone picking him up right away, and there is a someone you luck on the waiver wire, that seems to be your only option.
