Topamax and tired all the time

I started Topamax about 2 weeks ago; I still have the tingling in my hands, had headaches for the first few days, and I get so dizzy when I stand up that I usually have to sit back down... and I would love for the taste of metal to leave my mouth, I have already lost around 10lbs and didn't need to loose any weight in the first place, this makes me feel sick and frail. I'm already annoyed of people questioning my eating habits especially my parents, constantly telling me to eat; food just doesn't sound good. I am also very tired all the time. I just turned 20 and my doctor put me on this medication because I have been hospitalized for severe migraines even TIAs and he doesn't want me to be on birth control without being on something for migraines. I really don't like taking medicine every day, especially something that seems this serious to me, but I know that TIAs scare me more than a medicine. I increased my dosage last night and couldn't sleep at all. I'm really hoping that the dumb affect doesn't hit until after finals at least...
