The best I can offer is my sympathies and good thoughts. :( I'm sorry you're having to deal with this. My mom was a chronic migraine sufferer (they seem to have stopped with menopause, thank you God Above) and I well remember the sadness it cast on the household when we woke up to the sound of her moaning and dry-heaving.
If it gets unbearable, your doctor will have high-octane painkillers (go to Urgent Care if your GP can't get you in quickly). They'll knock you out for a couple days but anything's better than the migraine. And in the future, the best thing is to head it off before it starts. If you feel it coming on, attack it immediately. It is so much easier to stop them if they don't get a chance to really dig their claws in.
*hugs* I hope you get some relief soon.
