Amitriptyline in the morning?

I've been on amitriptyline 50mg for a couple of yrs. In that time the only time it has made me drowsy was the first two weeks of starting the meds. I've never, not even once been drowsy or sleepy since then. My sleep schedule has not been affected by the meds and I don't get insomnia. So I was wondering if I could switch to taking it in the morning since most of my symptoms are at their worst from morning til 4ish. What are your thoughts?
