Fellow medical doctors/medical directors, whats your round start set-up routine like?

Why do you choose iodide over charcoal? On the wiki charcoal cures better than iodide.

exactly as kiki said, you gain +2 TOX heal/tick at the cost of having to repeatedly refill them with literally everything else. if you want to fix someone who is in deep crit from poison, they will most likely be rolling for death at some point, so you need three things:
1: something to prevent death long enough for tox to heal. synap/atropine will buy you a lot of time 
2: something to fix what could already be 100+ O2, which can stack fast based on RNG. Defibs aren't always fast enough to pull out of death rolls
3: something to cure the TOX - this will take a long time to heal, TOX chems are so weak you're easily expecting 30+ ticks to heal already. 

for every tick charcoal has to work, you waste, on average, 0.5 units of *every* medicine inside them. this means you need between 2.25x to 3.5x as many units of every other chemical. (based on their depletion rates being between 0.4~0.2)
then consider how long charcoal takes to pull someone's health up on top of that, and you will lose out on a lot of expensive deep-crit medication, all for an extra couple TOX/tick
