I currenty take 60 mg a day due to narcolepsy. On this medication I only feel the need to eat once a day and even then I'm not eating much. I've always been a small person but when I went for my checkup a week ago I weigh only 90 pounds. What exactly are the side effects of weigh loss? I take three different types of Medicne, two of those being for narcolepsy and another for excessive headaches/migraine. It's hard to tell what some of the side effects are comeing from
