The availability of atropine should be changed a bit

It's specific thing is increasing sarin depletion rates hugely.

So you get hit with sarin, which is lethal, then you inject yourself with an auto injector that will do lethal toxin damage on its own and keep you from being able to reach charcoal... sounds like a great plan.
My suggestion- Reduce the Atropine in Atropine autos, and/or reduce its lethal and disorenting effects so its actually medically useful, the only time I see it being used is when doctors are dealing with a problem person and don't have a flash on hand.
