Topamax and ounce glasses

Hi, I'm 34 yo man from Spain, I started Topamax 3 weeks ago, first 25 mg at night then increasing 25 per week first in the morning then 50 in the night, next week I have to take 50 mg in the morning and 50 mg in the night and I'm really scared. About two hours after taking the pill, I can't hardly speak, i know the words but i can't say them, my head is buzzing, nothing is clear, I talked to my neurologist and he said everything should go in two or three months, but this is affecting to my job, i can't think clearly and i can't do anything right, i have to talk to my doctor to determine to keep on working or taking some days off. I have severe migraines since i was 24. I hope the side effects go soon. Excuse about my English, it's not good and I'm under Topamax right now.
