Using items from inventory

Hello all my game is coming along great thanks to all the help from everyone in the community i am here again to ask for some guidance I downloaded the free inventory system that Brackeys made available for free Unity Asset Store - The Best Assets for Game Making I got it into my game its working the only thing is that when I use say the water to replenish the thirst bar the hunger bar and energy bar also go up, and I only want to affect the thirst bar when I use the water here is the script

#pragma strict

//This script allows you to insert code when the Item is used (clicked on in the inventory).

var deleteOnUse = true;

private var playersInv : Inventory;
private var item : Item;

@script AddComponentMenu ("Inventory/Items/Item Effect")
@script RequireComponent(Item)

//This is where we find the components we need
function Awake ()
{
	playersInv = FindObjectOfType(Inventory); //finding the players inv.
	if (playersInv == null)
	{
		Debug.LogWarning("No 'Inventory' found in game. The Item " + transform.name + " has been disabled for pickup (canGet = false).");
	}
	item = GetComponent(Item);
}

//This is called when the object should be used.
function UseEffect () 
{
	Thirst.tcurHP += 25;
	Hunger.curHP += 25;
	
	//Play a sound
	playersInv.gameObject.SendMessage("PlayDropItemSound", SendMessageOptions.DontRequireReceiver);
	
	//This will delete the item on use or remove 1 from the stack (if stackable).
	if (deleteOnUse == true)
	{
		DeleteUsedItem();
	}
}

//This takes care of deletion
function DeleteUsedItem()
{
	if (item.stack == 1) //Remove item
	{
		playersInv.RemoveItem(this.gameObject.transform);
	}
	else //Remove from stack
	{
		item.stack -= 1;
	}
	Debug.Log(item.name + " has been deleted on use");
}

the problem starts at line 25 where I added the function to be able to use the pick ups any help on how to repair this will be greatly appreciated have a great weekend and happy game making. -K

In UseEffect() you increase both without anything that would filter (i.e if/then, boolean etc) which to increase. I can only guess that Energy is tied to Hunger and eating gives you an energy boost since there’s nothing else here that would affect Energy that I see.
