What did Jekyll experience as he underwent the transformation?

After years of work, Jekyll eventually created a chemical solution that would allow him to complete his work. Jekyll purchased a large quantity of salt for his final ingredient, and resolved to drink the concoction, knowing full well that he was putting his life in danger. The drink caused him pain and nausea, but as these feelings passed, Jekyll began to examine the results of his work. In fact, he felt strong, sensual and wild and he noticed that his body had changed. His hands were smaller and gnarled looking, and his clothes were suddenly far too large, which led him to conclude that his alter ego, which he later named Edward Hyde, was a small, dwarfish man. Jekyll reasoned that this identity was physically smaller because it represented his evil side which had previously been repressed and carefully controlled.
