seizures
"I started on Lyrica for my Simple Partial/Partial Complex seizures 5 years ago (by a previous neuro) and even though Lyrica was far from my current neuro's first choice he decided to keep me on it.  He immediately added Vimpat.  For the next 8 months, I had continued frequent spontaneous seizures and he persisted saying we just had to find the right dosage of both.  He'd change the dosage by 50mg increases, different times of day, etc.. 8 months of terrible short term memory, lethargy, and a rainbow of different types of seizures and as a last ditch effort he lowered my morning dosage by 50mg and I went from a zombie to ME again!  5 years and I had issues only when stressed or sensory over load.  But now they are sneaking back again..."
