Pregabalin
"Suffered a severe attack of shingles in early 2008 and now suffer from nerve damage and pain. I originally took gabapentin (most effective) along with morphine to deal with the pain. I developed stomach problems from that mix so tried Lyrica as a replacement to the gabapentin. My stomach problems have subsided but the Lyrica does not seem to be as effective at relieving the nerve pain. Even tried a combination of Lyrica and Gabapentin but no increase in effectiveness."
