[SOLVED] my thirst decreasing script doesn't work, help?

I made a server script and place it into ServerScriptService. The script is suppose to decrease their thirst and when I tested it I received no errors from the script and the script doesn't work at all. Can someone help me out here please? If you can then thank you!

Script:

print("Loading Thirst..")
wait(1)
print("Thirst successfully loaded!")

--//Services
local Players = game:GetService("Players")

--//Function
Players.PlayerAdded:Connect(function(Player)
	
	--//Variables
	local MaxThirst = Player.Stats:WaitForChild("MaxThirst")
	local Thirst = Player.Stats:WaitForChild("Thirst")
	local Humanoid = Player.Character:WaitForChild("Humanoid")
	local DecreaseRate = 1
	local SubtractThirst = 2
	local SubractHealth = 100
	
	--//Main
	while wait(DecreaseRate) do
		if Thirst.Value - 1 >= 0 then
			Thirst.Value = Thirst.Value - SubtractThirst
		end
		if Thirst.Value == 0 then
			repeat wait(2.5)
				Humanoid.Health = Humanoid.Health - SubractHealth
			until Thirst.Value > 0 or Humanoid.Health <= 0
		end
		if Humanoid.Health == 0 then
			Player.Stats.MaxThirst:Destroy()
			Player.Stats.Thirst:Destroy()
		end
	end
end)

Not entirely sure if this is the issue, but I think it's because you put:

if Thirst.Value == 0 then
	repeat wait(2.5)
		Humanoid.Health = Humanoid.Health - SubractHealth
	until Thirst.Value > 0 or Humanoid.Health <= 0
end

I don't know too much about the whole repeat thing, but this is my best guess as to what's wrong. Instead of using repeat wait(2.5) or whatever, try this:

if Thirst.Value == 0 then
	while wait(2.5) do
		if humanoid.Health == 0 then
			break
		end
		humanoid.Health = humanoid.Health - SubtrackHealth
	end
end

Not sure if I did much for you, but this is the best I got, I hope it works!
