Need function to action script 'exhaust'

[Zonkill]

Hey, so my problem is that i have script, but i don't know how to add 'Exhaust on use' as it is with potions.

function onUse(cid, item, frompos, item2, topos)
if getPlayerLevel(cid) >= 10 and getPlayerLevel(cid) < 12 then
 doRemoveItem(item.uid, 1)
 doSendMagicEffect(topos,8)
  doPlayerSay(cid," 1000 experiance Up",1)
  doPlayerAddExp(cid, 1000)
end
end

I will be thankful if someone may help me, Thanks.(rep+)

local exhaust = createConditionObject(CONDITION_EXHAUSTED)
setConditionParam(exhaust, CONDITION_PARAM_TICKS, 2000)
function onUse(cid, item, frompos, item2, topos)
if (getCreatureCondition(cid, CONDITION_EXHAUSTED) == FALSE) then
   if getPlayerLevel(cid) >= 10 and getPlayerLevel(cid) < 12 then
      doRemoveItem(item.uid, 1)
      doSendMagicEffect(topos,8)
      doPlayerSay(cid," 1000 experiance Up",1)
      doPlayerAddExp(cid, 1000)
   end
else
    doPlayerSendTextMessage(cid, 12, "You are exhausted.")
end
return 1
end
