I have anxiety issues and doctor gave me some 5mg tablets of valium for our last trip to WDW since I don't like to fly. I had to go to the dentist this am and felt anxious about going, so I took a 5mg tablet. ( I had never taken them when I had to fly). Even though I felt OK, when I was in the dentist chair getting worked on, my heart was racing. I have had anxiety attacks before and have had the whole racing heart symptoms but I was so surprised with the valium that my heart raced. I didn't have anxiety but had just the racing heart. When I left the dentist, my heart stopped racing. I hate anxiety! Is this normal for valium? Am I on the wrong medication? Thanks for any info.
