I've had migraines for years but worse since I had children. I don't get aura, but I have dreadful nausea. I am in so much pain i literally have to lie down flat and can't move because any movement makes me vomit, including just having my eyes open. I become extremely sensitive to light as well.
You need to track what triggers you. For me it is: exhaustion, dehydration, low blood sugar, intense screen work without a break for many hours (often so intense that I forget to eat and drink, worsening the problem). Also, bad PMT or sudden change in air pressure eg onset of a storm, can trigger me.
When prevention fails, then I use yellow and pink Migraleve, plenty of water, NO sugary food (no food at all usually, sue to vomiting, and sleep it off in a dark place in complete silence. Something cold on my head helps too. As soon as I can eat then raising my blood sugar is vital to feeling better, a piece of white bread is usually good.
Often I can sleep for hours and hours, and when I wake it feels like just minutes. It's an odd thing, as usually I have quite a good sense of time passing when I'm asleep. My husband often used to come and check I was still alive, lol, as I just would not move at all and he used to get worried. Now he knows if he leaves me, I will wake up recovered.
Next day I usually have what I call a "migraine hangover" - i am achey, exhausted, sometimes very hungry, and generally feel rubbish.
I am happy to report that since I quit my stressful job, I've had NO migraines on over two years. I think that says everything really!
