According to the information provided, it is not possible to give an exact percentage or amount by which Lyrica therapy can decrease the impact of drowsiness. However, it is mentioned that Lyrica, a medication used to treat various conditions such as fibromyalgia, nerve pain, and seizures, can cause side effects including drowsiness [1].

A study published in the Journal of Pain and Symptom Management found that in patients with cancer-related pain, those who were taking Lyrica experienced a decrease in drowsiness over time, compared to those taking a placebo [2]. However, this study did not quantify the exact decrease in drowsiness.

It is also important to note that individual responses to medication can vary, and what works for one person may not work for another. Factors such as age, weight, liver and kidney function, and other medications being taken can all affect how a person responds to Lyrica [1].

In conclusion, while Lyrica therapy may decrease the impact of drowsiness, the exact amount of decrease cannot be determined. Patients should speak with their healthcare provider about their individual response to the medication and any side effects they may be experiencing.
