If the drug doesn't help, you might consider trying the herb St. John's Wort (but not at the same time). I've been taking SJW off and on for about six years, ever since my dad passed away, and it really does seem to help. Of course, I've been back on it heavy again ever since my mom passed away in October.

It does take a little patience for it to work though. Most people don't notice any improvement until after about 3 weeks. That's because it helps the nerve cells in your brain to grow new receptor sites for the neurotransmitters that elevate mood, but without all the nasty side effects that most antidepressant drugs can cause.
