Ubrelvy works but shift the pain to neck?

I had Nurtec before and if it works it works. Now I’m taking Ubrelvy and…I’m not sure if it works cause you see after i took the med my migraine became like the fog. The head pain is gone but I can feel a bit off mentally and then my neck ache instead. So it shift the pain, something like that.

I also sometimes feel, at least when I first started, a light drowsy.

Anyone experience that before?
