i spent $500 putting drop bars on my flat bar despite lbs advice that the top tube was too long for drops. turns out they were right and ended up buying a well fitting road bike that minimized most of the wrist, elbow, butt problems. the real problem is that all bikes hurt somewhat. u just have to try to get to that point where the riding high outweighs the pain. it took me 9 mos of riding the flat bar for my body to adjust to drops. during that time i found that switching off hand positions to the end bars every 3-5 mins helped alot. good luck.
