You should be able to. Your Innocence type will probably respond best to the effects because of how it works. [trying not to think about the other thing inside Allen that might gain strength from this.]
You might feel a little tired after the effects wear off, though. You'll have to rest and catch up -- and eat a little more than usual [strange as that is to say to Allen Walker]. So I was thinking we'll just try a half dose this first time so it doesn't wear you out too much. The effect still should be significant.
