Topiramate
"I was prescribed this medication for my headaches from a possible concussion, or pinched nerve in my head. In just 4 days I lost 6 pounds or so, and have had all the symptoms: memory loss, confusion even to every day things (like why am I picking this coffee cup, or how do I cook this again?) blurred vision, and the crazy menopausal-emotional-roller coaster #understatement. Except drowsiness, and to some others here, severe depression. My possible concussion (whatever may be) keeps me wide awake, and what I like to call "wired" I was hoping for the drowsy effect, but it what it is. If you are paranoid, relax, its the drug, or just call your doctor for clarification. It seems, less active you are, the less side effects occur, at least for me"
