I Wish To Inform You That Taking Wellbutrin XL Was

I wish to inform you that taking Wellbutrin XL was causing me to fall backward. I decreased the dose to 150mg and have no problems since, but I still stagger when I walk. I am 83 years old and female. I do not get dizzy. I also take Celexa hbr 20mg. My physician is aware of this. All my labs come back normal. Can you suggest how to cure my staggering? thank you
