Hunger/Thirst is acting weird

[withpipeinhand]

Not sure if this is a bug or im just imagining things but i've noticed my thirst especially has INCREASED dramatically since adding the hunger/thirst reduction perk. It says the first level is supposed to reduce hunger and thirst by 20% but i have a feeling its doing the opposite as i recently only applied the perk and didnt have much trouble managing thirst or hunger before, i just wanted even more time before meals and canteen shots, yet im noticing again im going through my 4 shots of water faster.

Alternatively ive noticed that my hunger isnt going down nearly as fast (eating them roasted aphids) even though im running a hyperstamina build which if i read it correctly make me hungrier faster. I think this might be tapping thirst instead of hunger.

 

Either way i don't think either the perk is working as intended or hyperstamina is, because i cant get enough liquid now a days.
