now, i am on elavil for two days. But its side-effects are awful. I don't like drowsiness and sleepiness all along the day at all. Additionally, it didn't help my headaches. How long does it take to alleviate headaches.

I don't want to become addicted to this drug. Because, it disturbs my concentration and memory. Furthermore, Staying away alcohol for months because of this drug is not nice for me.

Is there any other drug (maybe a SSRI) to prevent chronic daily headache.
Is it true that elavil just masks the headaches, when you quit it, headaches will be back?
and finally, After how many days of usage does it possibly cause withdrawal symptoms while tapering?

thanks.
