It's especially so when she was trying to exceed the threshold alone.
Rex didn't know how it really felt for those he turned, but from her struggling expression each time she swallowed a mouthful of blood, it almost seemed like drinking his blood was akin to drinking alcohol when someone is not used to it.
Forcing oneself to drink it alone is quite impossible, as the body was fervently rejecting it.
