Yeah honestly I feel this.

I also think it's stupid that drinking a potion heals you instantly.

It's like bro, this is a magical potion, it heals by being digested, it should be several minutes before the effects even take place!

Having it take effect instantly implies that it's like, magical or something, and merely having it touch the inside of your esophagus is sufficient to apply the effects.

Totally immersion-breaking and ridiculous.
