Nothing has changed since yesterday. I'll be calling doctors' offices again today and waiting for answers. So far, the Nortriptyline does not seem to be making a difference against the headache. I'm also not sleeping well (though it supposedly has some type of sedative affect). Since I'll be adjusting the dose after a week, I'll wait and see if I just need a different dose. Of course, it could take 4 - 5 weeks to find the dose.
It's amazing I can feel the least bit depressed with both the Sertraline and Nortriptyline in my system, but I think I've pretty much reached the end of my patience. If I could just start getting some answers about anything, it'd help a lot.
I'll update if/when there's a change.
