I've dealt w headaches and dizziness for several years w no root cause identified. My neurologist put me on 25mg of elavil which I took last night for the first time.

Today I feel completely drained and my brain is kind of foggy. Not much appetite and while I went to work I def felt off all day.

Is this normal? Will it go away after some time? I want to give this drug a real try but don't know if I can deal w feeling this way forever.
