Hi,
Thanks for writing in.
Elavil or Amitriptyline is known to cause suicidal tendencies in teenagers and children. It is very important that you are monitored very closely by your prescribing doctor. Make sure to notify your doctor immediately if you experience any change in behavior.

There are other options for migraine like Imitrex which works well in children. It is also important that you keep a headache diary and try to identify a trigger for your migraines.
Avoid caffeine, MSG, preserved and processed meats and cheese.
Take care!
I'm sure if the dr. prescribed it for you then it's safe. I was on it, too and I definitely felt sleepier. Even that small amount made me sleep a lot better at night but I felt the affects the next day as well. I only took it for 4 months because it really wasn't working. But I also know that after I got used to it, I did not feel as sleepy. Your body will adjust some to that. Hopefully someone will come on who can tell you if there is another drug you can take. I'm sorry you have migraines. You remind me of me at that age. That's about when mine started.
