D. Heroin

Answer

**Step-by-Step Solution:**

1. **Identify the Symptoms**: The symptoms mentioned in the question are lack of sleep and loss of appetite. We need to find a substance that causes these symptoms.

2. **Analyze the Options**: The options provided are Morphine, Pethidine, Cocaine, and Heroin. We will evaluate each one to see which is associated with the symptoms.

3. **Evaluate Morphine**: Morphine is primarily a painkiller. While it can cause drowsiness, it is not typically associated with loss of appetite. Therefore, it is unlikely to be the correct answer.

4. **Evaluate Pethidine**: Pethidine is also a painkiller used during childbirth. It can have a sedative effect, but it is not known to cause significant loss of appetite. Thus, it is not the right choice.

5. **Evaluate Heroin**: Heroin is known to slow down body functions and can cause sedation. However, it does not typically lead to lack of sleep. Therefore, it is not the correct answer.

6. **Evaluate Cocaine**: Cocaine is a stimulant that increases energy and can lead to feelings of euphoria. It interferes with neurotransmitters like dopamine, which can result in a lack of sleep and loss of appetite. This makes cocaine the most likely candidate for the symptoms described.

7. **Conclusion**: After evaluating all the options, the substance that causes lack of sleep and loss of appetite is Cocaine.

**Final Answer**: Cocaine
