I'm so thankful to have found this. I had food sensitivities before I started taking it and they have increased. You wouldn't think so because it's an H1 antagonist, but there is definitely something going on. I'm going to get off of it and try zoloft. Can anyone tell me if their symptoms to food went away after they stopped mirtazipine? This has been so hard. 3 allergists told me the sensitivities are stressed related, but I know there is something else at play.
