are you clicking your button again? It won't do it all with just ONE press. You will have to push it again to get Drain Lift to cast.
Gurb is very correct. 1 spell = 1 button push.

If you're not pushing the buttons that often, then you're using automation which is essentially botting. So, sadly , we have to push a button for every global cooldown.
