I just started taking Tecfidera a week ago. I'm wondering if anyone else is having a hard time with it. I have no appetite what so ever but I feel like I have not eaten in years. I'm beyond dizzy and can't stand too long because I feel like I'm going to faint. I have only vomited once. I have experience flushing twice but its not a huge issue. I just want to feel normal. Is this just nausea and GI issues? What has everyones experience been like?
