This is pretty much my list as well, sans the weed because my sense of smell is too sensitive during a migraine. The ice packs are the thing that pushes me over into recovery territory.

You don't need anything fancy, get 2 gallon baggies, fill one about halfway with ice, add a little water, and then seal it up inside the 2nd baggie. I rest my head on it like a pillow but i have a lot of hair that acts a buffer. If it's too cold, wrap it in a thin kitchen towel.

Then I let time and rest do its thing. If the ice has melted and the migraine isn't gone, I make another bag.

Someone else mentioned the ice packs, which besides the weed is the main thing from that list I haven't really tried already. I'll have to give that a try since I do have some ice packs in the freezer...not sure why I haven't thought to try it. I'll probably pass on the weed though. Between legal issues with it where I live and just overall poor experiences in the past with it, just doesn't sound appealing. Glad it helps your wife though!

And fortunately I was able to get in touch with my neurologist, who set me up with a round of prednisone. That seems to be helping, which is a huge relief.
