Yes they really did and we had another hot day today. But they drink a lot and have enough shade and a cool apartment. Right now, since it's evening, they enjoy it outside again :-)
It really is true. You just never know when the next one hits. Which makes it especially difficult if you want to make plans for something, since you just don't know if you will be alright on that day.
Caffeine is a good thing for migraine! It also helps other migraine meds to work better.

Hope you have a lovely Friday ;-)
