I have been taking Lyrica successfully for about nine months. For the first six weeks or so, there was a definate problem with fatigue and dizziness for about two hours after taking it. For that reason, my doctor had me take it at bedtime and two hours before I would normally get up. This meant I took it at 8:00 pm and 6:00 am. Once we got beyond this, a third dose was added with no difficulty. Good Luck.
