Migraines starts when I relax and then goes away when I make myself busy?

So lately I have been noticing whenever I take a rest for the day and start to relax I immediately get hit with a wave of sleepiness. Then the head pressure sets in, the slight nausea, feeling warm, all my classic migraine signs. But about 90% of the time if I get up and start making myself busy, like extremely busy, on my feet cooking or cleaning for hours, then it goes away? It’s the strangest feeling. Normally I would have to take an ubrelvy or excedrin but just being on my feet takes it away?

Has this happened to anyone?
