Hi again, MK2019! I hear how frustrated and discouraged you are feeling. It is hard when migraine attacks change not to blame yourself and to feel all sorts of guilt. Whether or not your use of Advil could be creating medication overuse headache and an increase in migraine days, try not to blame yourself. The disease produces horrible symptoms, and sometimes the treatment can as well. You are doing the best you can to manage with a rotten illness.
Others in the community have also dealt with an increase in migraine symptoms because of the overuse of medication. I thought this article might be of interest to you:

I would encourage you to discuss your Advil use in further detail with your doctor and see what s/he recommends for you. Breaking an overuse cycle (if indeed that is what you are experiencing) can be incredibly miserable, but the result may be better management of your migraine symptoms. If you haven't discussed this possibility with your doctor, I encourage you to do so. Please keep us posted on what you learn and how you are managing. Wishing you a gentle day. ~Allyson (Migraine.com team)
