Mac123, I'm almost 3 weeks post-removal and I too have had more bad days than good. Still foggy (like I'm not really here), anxious and worst of all, I've had 2 migraines in the last week (considering I haven't had them at all for the last few months).
I feel disappointed with my recovery too, but am hopefull things will start to change once I've had my first period. I immediately went on my old BC pill when the IUD was removed, so what I'm experiencing this week should be PMS.
I'm on zoloft and xanax for the anxiety and started taking all of my vitamins again (D, Calcium, Magnesium, Multi, and Fish-Oil) and hopefully those will help to bring me around quicker.
