Hi Laura. I have been 28 days now without Lyrica but I tapered slowly for the last couple of months. I still have terrible problems but there is a slight improvement most days. Re anxiety & sleep, for me, when I worked out it was the Lyrica I was able to relax more because I knew I would get over it eventually. It was when I did not know what was wrong and I was imagining I had some horrible new medical development that I was most anxious. I tried Promethazine for sleep once and sometimes have a scotch before bed but try not to.
