I very much agree with @closetmonster93 when she says "I realize that medications work differently for everyone and not two people are the same. So what may work for one person doesn’t necessarily work for another person and vice versa". Each body is unique, as my doctor tells me. I also tend to be drug-resistant to a lot of these medications, having already tried Lamictal, Tegretol, Trileptal, Gabapentin and Vimpat, which caused me more harm than benefits. I have been taking Keppra since last December. At the beginning, I struggled much with the side effects, but little by little with the fine-tuning and dosage reductions done by my current doctor, I have been feeling better. My doctor says that my body works like a child's, respecting it and not following the standard protocols.
@earlylonghauler, I am sending you here a Mayo Clinic link containing information on Briviact. The ones I read from other AEDs on Mayo Clinic site were more complete than the leaflet that accompanies the medication.
