Ok, a few things:

1. F that guy.
2. I also don’t drink much due to my migraines. I’m not a huge drinker anyway, but I abstain primarily because I know alcohol is a trigger for me. If it’s a special occasion and I want to drink more, I just have to accept that I’m going to pay for it the next day. (Especially because I have a six-year-old who doesn’t want to let Mommy rest for too long.)
3. I also “only” get around 10 migraines a month. They were much worse when I was a kid, but I didn’t understand my triggers back then. And I have better meds now. But I still have to deal with them and some months are worse than others.

Best of luck with everything! I feel your pain — literally!
