First dose of Aimovig for Migraine

I've just received my prescription for my first dose of Aimovig for chronic migraine and wondering if anyone can share experiences of how they felt after their first dose?
I would like to take it straightaway as I've had a bad time the past couple of years in late spring/early summer so I'm hoping the Aimovig will help. But, after a couple of Covid years, I have a lot going on over the Easter holidays, including seeing family I haven't seen since Covid on a short holiday and I don't want to ruin that. I'm especially concerned that a hotel stay with no kitchen facilities might not be a good idea if I'm trying to avoid the constipation side effect of the Aimovig. Any advice?
