Hi Rubylizard. Congrats on your upcoming wedding!

I think everyone gets nervous about weddings, but when you have anxiety problems of course it's more nerve-wracking. My anxiety makes me nauseous and gives me IBS attacks. You could use an anti-nauseant -- something natural that won't make you drowsy. I like ginger capsules to keep the nausea away. Drinking ginger herbal tea helps too. Knowing that I have taken something that has anti-nauseant properties also lessens my fear of getting nauseous or sick to my stomach. I also take an Imodium just in case for really important events.

I learned a technique for dealing with the lightheadedness that goes with my anxiety too. I actually saw this on Dr. Phil. If you have to stand for a long time -- like standing at the altar -- and you start feeling lightheaded and nauseous, flex and unflex your leg muscles while you're standing there. I forget WHY it works -- something to do with bloodflow. Apparently, it's what pilots flying at Mach speeds do so they don't pass out or throw up.

I was having my haircut one day (I had very long hair at the time) and the stupid stylist made me stand up for the entire time. I started panicking and getting nauseous and feeling like I was going to pass out... Then I remembered that episode of Dr. Phil, and started flexing and unflexing my leg muscles, and very quickly I started feeling better. I did that throughout the haircut, and felt fine.

If you have some techniques and precautions in place -- just in case -- it might make you feel calmer so you can just enjoy your day. All the best!!!
