ULX Stuck cooldown/grenade block

[HyperDrive]

Alright, I have a "stuck" command that runs through ULX admin mod. It works very well, but it is very exploitable. The code is this:

function ulx.stuck( calling_ply )
	if not calling_ply:Alive() then
	ULib.tsayColor(calling_ply, _, Color(255, 0, 0), "You can't do that!")
	else
	local pos = calling_ply:GetPos()
	ULib.tsayColor(calling_ply, true, Color(189,236,182), "You will be respawned in 5 seconds. DONT MOVE YOUR MOUSE OR TRY TO WALK!")
	timer.Simple(5, function()
		if IsValid( calling_ply ) then
			if calling_ply:GetPos() == pos then
			calling_ply:Spawn()
			calling_ply:SetHealth( 50 ) 
			ULib.tsayColor( _, Color( 255, 0, 0), calling_ply:Nick(), Color(0, 0, 255), " has been unstuck!")
			else
			ULib.tsayColor(calling_ply, _, Color(255, 127, 0), "You moved during respawn cool down. Respawning aborted.")
			end
		end
	end)
end
end
local stuck = ulx.command( "Prophunt", "ulx stuck", ulx.stuck, "!stuck" )
stuck:defaultAccess( ULib.ACCESS_ALL )
stuck:help( "Respawns you after 5 seconds if you're stuck" )

I want to add in a cooldown timer so people can not use it so often, lets say 10 seconds. Also hunters get a smg grenade on respawn, is there any way to fix or block that? If not, how do I strip their weapons and give them back different ones?

or

-- Thanks KingofBeast for help
-- Initialize this before player respawns
if IsValid(ply:GetWeapon("weapon_smg1"))
   local grenade = ply:GetAmmoCount(ply:GetWeapon("weapon_smg1"):GetSecondaryAmmoType())
else
   local grenade = 1
end

-- Run this after player respawn
if (grenade == 0) then
   ply:SetAmmo(0, "SMG1_Grenade")
end

I also recommending doing something like

local plyHealth = calling_ply:Health()
calling_ply:Spawn()
calling_ply:SetHealth( plyHealth )
