After a two month taper/highest dose 175, I stopped Topamax mainly because I was slurring and unable to complete sentences. My biggest drop was 175 to 150 for two weeks. I was on Topamax for 4 months. It has been 2 1/2 weeks since I took my last dose. I am asking if anyone can offer some encouragement. Has anyone had withdraws that exceeded the 2 week mark. I can deal with this if I know others with similar experiences. My only side effect is terrible fatigue.
