hey. from what i know... dx isn't as important as an adequate view of your symptoms. medications tend to target symptoms rather than dx's, though some symptoms cluster and medications may target multiple symptoms while others might be more specific in their effects.

your doc said that you didn't have manics. i would say something to them about how you weren't thinking of manics you were thinking of hypomanics. re medications different people (with the same symptoms) find themself responding differently anyway, so i would say it is definately worth a try to take it and see if it helps. if your depression followed on the heels of a manic / hypomanic episode then it might be worth mentioning it...

sometimes mood stabilisers like tegrotol or epilim (sorry don't know whether those have different names where you are) can help with levelling out mood. i think that lithium (in particular) is a medication that tends to be reserved for true manic episodes as dosage needs to be very carefully monitered.
