Hello and Welcome.
I'm sorry to hear about your migraines. I am fortunate that I don't have chronic migraines - but I've had them periodically. Mine become blinding accompanied my nausea and vomiting. Opiates have helped when used in combination with other medications but not alone.
You've been offered some great information - by ppl that have more personal knowledge than I.
I can tell you that Dilaudid is a stronger opiate than Percocet - but your physician may or may not RX it for you. What other medications are you taking to help with your Migraines?
We have a forum that is directed at Migraines and Headaches. You may find more information at that forum.

I hope we've been helpful - and I wish you the very best. Please post again - we'd like to hear more from you.
