seizures
"I have had grand-mal seizures since age of 15.  Around 32 I started having partial seizures only I didn't know that's what they were till I read a pamphlet in my Drs office.  They put me on Vimpat, which at first did not help with the dizziness I was already feeling from the partial seizures, but after about a year now the dizziness has definitely slowed and I only have partial seizures when I'm overly, overwhelmed, or stressed.  It doesn't help with my grand-mal seizures which I have at least 1-2 every month. I have noticed weight gain, and memory loss which I had before the medication, and hair loss, and tingling in my limbs, but if I drink more water it helps with the tingling. As for the hair loss I take biotin and that has helped."
