Started pregabalin/Lyrica 75mg x2 for horrible crippling anxiety and insomnia 3 days ago. So far have felt a little calmer but anxiety has not gone. Also still not sleeping so well. After reading so many posts on this site saying it's a magic drug that works straight away I am getting a bit worried. Am I expecting too much too soon? Has anybody found it can take a while to build it's affect for sleep and anxiety or should I give up now?
