Hello, we've never met before, but I wanted to offer you a couple of suggestions of the herbal kind. There is Valerian Root, it is the deritive for valium, but not narcotic. It comes in both capsule and tea form. There is also Chamomile tea that helps to calm the nerves. Perhaps you can have some of that in the morning before work instead of coffee, it has no caffeine that can add to nervousness and "the shakes". There is also something called "Rescue Remedy" from the Bach line of products.
Granted, these are not the same as Klonopin, but they may help you enough to get through the day a little calmer.
Hope this helps.
Congrats on the new job, it'll be good for you. There's nothing like putting your head on the pillow at the end of the day and feeling like you've been somehow productive.
We're here for you.
TgrsPurr, xo.
