Based on the information provided, it is not possible to definitively conclude whether Lyrica (pregabalin) induced sleep disturbance is permanent.

According to the drugpatentwatch.com page for Lyrica, it is a medication used to treat various conditions such as epilepsy, neuropathic pain, and fibromyalgia [1]. However, it does not mention any information about sleep disturbances as a side effect or its permanence.

The NCBI article discusses the potential side effects of pregabalin, including dizziness, drowsiness, and fatigue [2]. While it does mention that these side effects may decrease over time as the body adjusts to the medication, it does not explicitly state whether sleep disturbances are permanent or not.

Medicalnewstoday.com also lists sleepiness and fatigue as potential side effects of Lyrica [3]. However, it does not provide information on the permanence of these side effects.

Therefore, while sleep disturbances may be a potential side effect of Lyrica, it is unclear whether they are permanent or not based on the provided information. It is recommended to consult with a healthcare professional for personalized medical advice.
