Thanks Sheila.
Thanks Sara.  I'll be sure to look for feeling tingly or lightheaded or hot.  I knew about the calm feeling and look forward to that.  As for stopping cold turkey, I definitely don't intend to do that, nor to stop at all.  This is something I have thought through meticulously and have also done a lot of reading on the subject. I had the "Wow, I'm doing something to myself permantly that will be with me forever" thought and although a little scary at first, it makes me happy.  It's kind of like moving to a new house.  You don't know what lays ahead of you for certain, but you know you need to move on.
Thanks Beth.  The doctor did tell me about it being a diuretic, but I didn't know that the dehydration would be the cause of it.  Maybe it's a stronger diuretic than caffeine though.  Anyhow, I'll just drink lots of water anyway.
