Hello Nicole,
I did go dairy free (along with Gluten and caffeine) and not only did I lose about 8 pounds, I did seem to have less severe headaches and less quantity. I thought giving up ice cream was going to really stink, but I'm finding I really crave C H E E E E E E S E ! This year I have had some cheese on occasion and seem to do okay with it, although parmesan may be a culprit. "They" say the aged cheeses are really probelmatic for migraneurs and I've noticed the 2 times I've had parmesan, within 48 hours I'm getting a significant headache.
I would suggest to absolutely try it. Read how dairy effects our bodies, it's not good anyway and will make it easier to forgo. And if you have the stomach for it, read up on the dairy factory farming industry. It's horrible!
The coconut milk and cashew milk "ice cream" is freaking delicious. You'd never know it wasn't real ice cream. I get the So Delicious brand when they are on sale. Yummers.
Good luck, let us know!
Cheryl
