they called the Drink 
poison im like why did he do that and what is the "heavy cost" they are talking about? isnt it technically a potion with side effects i mean if it causes a bulk up but a trade off happens thats the negative effect.
I mean alcohol is technically a poison and many drink it. Also there was this one dude in anchient rome that drank small amounts of poison to build up a immunity cause he thought someone wants to poison him. Then he was captured and tried to kill himself with poison, but was already immune to it...
Aphelios? its part of a ritual im pretty sure
Juliet drank poison when she found out Romeo stabbed himself. Romeo would still be alive if the dumb slut wasn't such a heavy sleeper.
