After five days it still hasn't quite reached a steady plasma state. Give it a little more time. For most people 1 mg/day does the trick. Give it a fair shot and if it doesn't help in, say, eight days, consider (with your doctor's consent) raising the dosage. And if that doesn't work, then you need to consider another medication because you don't really want to be in a situation where you're taking a high dose of Klonopin and have to taper from it.
So, four more days on 1mg/day, then reevaluate with your doc.
A lot of people don't like benzos, but one thing is for sure: they're almost universally effective. Very straightforward in how they work. Provided your diagnosis is correct and there's nothing else going on, the Klonopin should give you some relief. It is subtle, though.
Another thing I forgot to ask is if you're taking the real deal (Roche Klonopin) or a generic? Benzos have a very narrow therapeutic index and a switch to a better generic might be good for you. I've had good luck with Caraco.
Best of Luck,
