I'd stay away from drugs without consulting a vet.
One of mine suffers from this, too, so I know your pain. I've read everything I can find on the subject, and there are no easy cures.
The best advice I've heard is to crank the TV or turn on some soothing music. Recently, someone posted a thread saying a tightly fitting coat helped with her dog's fear of thunderstorms. Whether it cuts the static electricity in the air or just comforts her is up for debate, but several people said it works. Here's that thread.

If you use anything to calm her, I'd suggest Rescue Remedy. You can buy it at most pet stores, and my understanding is it's mild but effective.
One thing to be careful of is coddling her when she gets scared. I know it's impossible to resist, but that just reinforces that it's OK to get scared.
Good luck.
