I am sick...again. How does this happen? I slept a lot last weekend and still I'm averaging around 5 tissues an hour. The pressure inside my head is so bad that I have to pop my ears to release some of it, like when you're in an airplane. Even my new mega-vitamin couldn't prevent this. Yeah, look and those ingredients, folks. This ain't no Flintstones chewable. But apparently 2500% of my daily allowance of thiamin isn't enough.
