I am supposed to be starting out at 100 mg for first few days and increase to 200 mg if well tolerated. I ended up breaking the pills in half and only taking 50 mg for first two days because I am terrified of having a seizure. I am already feeling side effects on this low dose, jittery, tremors, restlessness but feel tired at the same time. Is this normal? Also, is anyone taking this as a migraine preventive? That is why I am taking it as well as being depressed.
