I have the same problem with allergies. It's not so much the "room spinning" kind of vertigo, but I can just be sitting there, and all of the sudden I feel like I'm falling, or sometimes it feels like the floor is moving under my feet. When I walk, it almost feels like I'm drunk, like my equillibrium is REALLY off. I always have this "off balance" kind of feeling. Meclizine does not work for me. Like UCLA_Girl said, when I took straight Sudafed, it helped dramatically.
My problem is, I also suffer from anxiety and panic disorders, so sometimes the Sudafed ramps up my anxiety. I have found that taking Advil Cold & Sinus gives me the same relief because it contains psuedophedrine, so sometimes I will take that with a Benadryl, and that works perfectly. I hope this helps some of you, and I'm SO happy to have come across this post! I was afraid that I was the only one this was happening to.
Oh! And I also suffer the "not being able to walk down the street" without feeling REALLY funky. I suffer the most ALL summer, from the end of June/beginning of July, until the end of fall due to my allergies to 7 different types of mold spores and dust mites.
Lord, Please calm my heart & my soul today. So many things are out of my control and I need your love to soothe me and calm me. YOUR love lets me know it will be OK.
