Elavil is the same as Amitriptiline. Too bad Imitrex does not work for you. I used Midrin several years ago and just started the taking so much and then needing another. I forget the term at the time. I try to be sure I do not do that with the Imitrex. Otherwise, it will eventually cause "rebound" headaches. "Rebound" was the word I was looking for.

Not sure if this has anything to do with my headaches lessening; but after developing PN, I had Vallium added to my regimine of meds. Vallium is to help with anxiety, but also muscle problems. When I get a migraine, it usually would start on the left side; but the neck and shoulder muscle would also be involved. Since being on the Vallium (could be a coincidence) but headaches have lessened greatly. Again, also am careful not to take too many Imitrex as to not cause the "rebound" effect again, which just makes the headaches clear up for a short time and come back with a vengence.
Hope you are able to find something to help. These headaches can be so debilitating.
