Try lowering your seat enough that the weight is on your...seat...not your wrists?

Seriously, that's the first, and cheapest solution to that problem normally. Then I'd recommend the trekking bar if you're still having an issue with pain. A drop bar will not give you more riding positions, especially if your a larger rider. You'll just be crouching into a tight ball trying to maintain control of the bike and not spew your lunch. YMMV.
