Ugh...you poor thing. I thought I was the only one who had the "shake, rattle and roll" thing. It's the most awful feeling to not be able to control it, isn't it? I figured mine was related to anxiety as well...you know how the doctors have you convinced, once you have anxiety, that EVERYTHING that's wrong with you is directly related to that. I just thought I was nervous over having an IBS attack, so I was shaking. In a weird way - and not that I would ever wish it on anyone, EVER - it's nice to know that it could just be an IBS thing.
I hope you all are feeling much better today - keep your fingers crossed for me, please, I've had a really rough 3 days. Actually called in sick to work today - yuck.
