Hi, I tried Lyrica for about 6 weeks but had to discontinue it. It made me tired, cranky, spacey and only minimally reduced my headaches. After stopping it , i had a three day migraine, but now am back to normal.(??) I know we are all different, but I really did not like the way it made me feel. I started at one, then two, then three 3 75-mgs a day. But I felt cloudy in the brain and feel so much better after being off of it.
I hope you have better luck with it, but if the mood swings continue, I'd reconsider.
