Valleybob,
Amitriptyline will make you crave carbs...sounds like the opposite of Topamax
If you don't have issues sleeping then Notriptyline may be better fit for you since it has less side effects but if you suffer from chronic insomnia like most of us here, the Amitrypline has a nice sedative effect. I take a dose during the day too which mellows me out. Guess that's why it's an anti-depressant.
