I was walking across the garden after breakfast, enjoying the clear wintry air, when suddenly my body was again torn by those indescribable feelings which I always experienced after a dose of the drug. I only just reached my study before I was again burning and freezing with the violent passions of Hyde. With feverish speed I mixed the drug. This time I had to take a double dose to return to my old shape. And then, only six hours later, the pains returned and I had to repeat the dose.
早饭后，我去花园散步，呼吸呼吸冬天里凉飕飕的空气。突然身体又是一阵剧痛，就像每次吃过药后无以名状的痛苦折磨着我，刚刚碰到书房的门，心里又是一阵翻腾，忽而冰冷忽而灼热，充斥着海德狂野的欲望。我急不可耐地配了药，这次喝了双倍剂量才使我复原。但是，六个小时后，剧痛又回来了，我又得服药。

From that day onwards the situation worsened. I needed larger and more frequent doses in order to stay in Jekyll's body. The pains came unexpectedly, but most of all when I was asleep. I was afraid to go to bed, or even to sleep for a few moments in my chair. If I did so, I always woke as Hyde.
从那天起，情况恶化了，药量大了，次数也多了，只有这样才能维持着杰基尔的外貌。不知什么时候，痛楚就来了，尤其是睡觉的时候，我甚至害怕去睡觉，哪怕在椅子上睡几分钟。只要稍稍打一会儿盹，醒来就又变成了海德。
Soon Jekyll was a sick man, feverish and weakened by pain and fear.
很快，杰基尔就成了一个病人，被发烧、疼痛和恐惧折磨得十分虚弱。
