After 2 months on Motegrity (generic for the past 5 weeks), I have started having bad dizziness every day that hampers normal activities. But this didn't start when I began with brand-name Motegrity. I take it with lots of water all day, and CALM, a magnesium oxide supplement powder, recommended by my gastroenterologist. I don't know if the dizziness is caused by Motegrity affecting my brain or if it is unrelated. I do not have positional vertigo (BPPV) but it feels like vertigo. I don't drink, either, but I feel like I did in my 20's after getting drunk. Not the brain fuzziness, just the unsteadiness. It also makes me feel nauseous. Motegrity has allowed me to have much less constipation, the first treatment to help, so I need to know if I should keep taking it or get off it. My gastroenterologist and his staff have too little experience with the drug to tell me one way or the other.
