Occasionally I miss a dose of Pregabalin, my mental health medication for my anxiety. I take 300mg of Pregabalin (Lyrica) twice a day and have been for about 18 months now. Saturday night I fell asleep early and forget to take my medication. Sunday I felt, well all I can really come up with is odd. I was more touchy and short tempered – sorry family. But what I really noticed was that I was so itchy.
