I was just wandering if anybody has had success with amitriptyline?

I've had CDH for about 3.5 years now and a little less than two years
ago my doctor put me on 25mg of amitriptyline. It "helped" a little,
and then he put me on 50mg daily. That was followed by about 9 great
months where I would go weeks without a headache, or when I did get a
headache, it didn't last days. I was so happy to say the least. The
past several months my headaches have been getting progressively worst
and the past weeks unbearable. A couple weeks ago another doctor put
me on 25 mg of nortriptyline. That didn't seem to help, so now I am on
75 mg of amitriptyline daily and I am told I need to wait several days
for the effects to be felt, if at all?

I just want to if anyone has ever had success with it or was it just a
coincident.

If my headaches don't improve, I may drop out of college. I can't
imagine being an accountant with a headache all the time. Starting a
new career seems impossible right now. I really don't know how I
haven't killed myself my now. I guess just hoping for a few good days
keeps me going.
