I have been going crazy debating whether or not to take this medication for my migraines that recently developed a month and a half ago because I am worried about the pill causing me to gain weight like most females tend to worry about . So is it the pills itself that cause weight gaining or the increase appetite it causes that makes you eat more or want to eat more therefore causing you to gain weight on your own . If I control my portions and make sure I don't eat a lot of crap should I be fine ?
