It depends on your benzo tolerance, and how much Xanax you are taking. You should feel something, though. Klonopin is a very good muscle relaxant, and is more sedative in action than Xanax at equal doses for anxiety relief. 0.5 mg Klonopin is the lowest dose pill they make, but don't let this full you, Klonopin is very potent. Some charts say twice as potent as Xanax per mg. So 0.5 Klonopin = 1 mg Xanax. Other charts say they are equal mg per mg. Either way, it is potent. BUT, Klonopin doesn't pack a punch like Xanax does, and takes some time for the effects to kick in, they also last much longer than Xanax's effects. It will be a good addition.
I don't know what you are saying about tramadol, though. Becareful with mixing opioids and benzos.
