For those taking amitriptylin / elavil, how did it affect your appetite?

Hey all, I recently started taking amitryptylin (around 2 weeks now) and it's working really well for my migraines, but I have noticed a pitless stomach feeling like I am constantly hungry since I started taking it. Has anyone else experienced a change in appetite (up or down) when starting this, and how long did the side effects of that last?
