Bonkate,   The half-life of Wellbutrin is 21 hours, so it took about five days for it to be out of your system. How long withdrawal symptoms can last depend on many things including all health issues you have, your general health, and other things. Your doctor is the only person who can really tell you if you should be past the withdrawal symptoms by now.   Another unfortunate problem we can have is that once we go off a medication that was helping reduce our Migraines, it may or may not work again for us.   I wish there were simple answers to this, but there simply aren't. You're going to have to work with your doctor to see if Wellbutrin will work for your Migraines now, or if you're going to have to try something else.   If you'd like to talk with other Migraineurs and get some additional information and support, come join our discussion forum. You'll need to register again once there because it's a separate membership database, but you can use the same member name, email address, and password that you used here. You can find our forum at http://forums.healthcentral.com/discussion/migraine/forums.   Good luck, Teri
