No, but if you use the off-hand Roar of Persuasion, that gives Life Drain whilst Wrath of the Berserker is active. The health gained from the Life Drain completely off-sets the health cost of Whirlwind that Fallow Field causes. As you can mostly likely maintain close to (or actually) 100% up-time on Wrath of the Berserker, effectively the off-hand negates the health cost of the main hand, so you can Whirlwind indefinitely.
