OMG! I too had the same reaction. However, didn't make the connection until I had another one. The first time I was drinking it while in a local home improvement store picking up acoustical ceiling tiles. Just assumed it was something in the store. I was sneezing so hard I could barely make it through the check out. I couldn't speak because I was sneezing every few seconds. Never experienced anything like that in my life. The second time I just picked one up on my way home from work. Sneezed for hours, this time though, it also seemed to affect my upper respiratory too. Thankfully the sneezing fit was not as bad as the first time. Just extremely obnoxious and very unpleasant. I looked up the ingredients and it doesn't look like anything major. I'm also not allergic to any foods, or nuts or berries... I can't imagine what it is... and it really stinks, because they taste soooo very good!
