postherpetic neuralgia
"Got shingles on my scalp and face, was treated with Valtrex, Neurontin,and pain medicine. I have repeatedly had bouts of shingles for the last 15 months, resulting in PHN. I now take Lyrica, 1 at 8 am, 1 at 3pm and 3 at bedtime. This dose was gradually increased over time. Although very fatigued I am 50% better and am able to function better. The initial drowsiness subsided after a couple of months. Do still have a bit of brain fog, not sure if it's the Lyrica or lack of sleep."
