I've been on and off lyrica since september 2013.. All I can say is that this med can be extremely effective to treat SA, and GAD (something that I personally have in addition).
I started with zoloft, which did not work. Tried numerous other meds, until my doctor decided to prescribe me Lyrica.
I was told to take 1 pill, 75 mg "when needed"; as a means to calm my anxiety and OCD. And to start with, I thought that had thrown my money in the trash, because this dosage did not work. However, I remember one night where I was feeling very anxious, and read that the dosage could be higher, so I tried 2 pills.. then I tried 3.. and 4.
At this point, I felt as if my anxieties were gone, in addition to the feeling of general well-being. And I knew that I've found my med. My dream med.
Months later, varied doseage, and 150mg/day, and a couple of depressing withdrawals from Lyrica, I have much more respect for this med than I did.
It works VERY well. High abuse potential. Do not exceed the prescribed dose. The withdrawal from Lyrica can be insanely depressing and tough. It's a med that demands a ton of respect, for it's power.
