Title bout sums it up....Anyone else?

For the past 2-3 months it has probably happened more than a dozen times where I will start feeling really sick one day, thinking "Oh crap, well there goes my week." Only to wake up feeling perfectly normal. I get the really blatant impending sickness feeling and I've even gotten a little stuffy and sick to my stomach a few times, then go to sleep hoping I'll be all right, then I'm fine the next time. Most of the time I don't even think of how I felt the previous day because I feel so normal. I will realize days later that I was pretty sure a few days ago that I was going to be sick...

It's really odd...and I don't think I've *ever* had this happening previously in my life. If I start feeling sick...I get sick. That's how it's always been.

How bizarre!
