Too much Sulfite

[Kelbor]

I way over sulfited some peach mash....stupid mistake. Waited a week, dropped a yeast bomb and out started rocking. Cap fell, strained it, let it somewhat clear and now it its a month later. Running it I'm getting a gnarly sulfer smell on the distillate. Am I screwed? Will out evaporate off at ask before I lose abv? This its a strip run I'm doing right now....

Thanks
