Hello, side affect's are Short Term Memory lose and long term memory lose. We have friend he was on them 4 then 6 a day. He has a cat after 8 year's owning his cat he would call my wife ask Tammy what's name of my cat ?? So we told him get off them fast start with Lyrica he is doing so much better for his pain. Pill is not worth loosing memory as you won't get it back. Doctor's are pushing Gab's because of ** taking our pain med's away. Blessed Evening, Jay
