I know that medication overuse causes rebound headaches. I know that I have probably developed Transformed Migraine and suffer daily headaches because of medication overuse, after decades of suffering from migraines. I have desperately tried to stay away from all medication for 1 week to try to break the cycle, but the most I've managed was 4 excruciating days. Does anyone have any ideas on how to break this maddening cycle?


Medication Overuse Headaches (MOH) is an awful thing. My heart goes out to you. First of all, see your doctor to be sure what you have is actually MOH. Although most people with daily headaches do have MOH, it is possible to have chronic daily migraines that are not MOH.
You will most likely need a doctor's help, then, to get out of rebound, if you are actually in rebound. If you do not see a headache specialist, it's time to find one to get the help you need. There is a list of headache/migraine specialists on this site. I am not clever enough to get the link into this post, but someone else will be. A headache/migraine specialist is the best person to help you work your way out of rebound.
You will ultimately have to stop the "offending" meds in order to get out of rebound, but let a doctor help you through that process. Sometimes there are things the doctor can do to help you through the worst of your withdrawal.
We will be here to support you as best you can. I encourage you to visit our discussion forums if you haven't already. To get there, click on Migraine Forums under the orange Manage bar. Registration for the forums is separate from the registration for this page, but of course, you can use the same information to register. Some of our other forum members have been in rebound (miraculously, I avoided it myself, despite a short period of chronic daily migraines,) and they will share their experiences and support with you.
Good luck with this process. It's not easy, but there IS a way out.
