Bless your heart. I can't imagine what you're going thru. I know when I'm extremely anxious, I shake but I know that's not what you're talking about.
Have your doctors tried Inderal? It's also known as Propranolol. It's often used for Essential Tremors and is very effective! I was just wondering if they'd had you on this or not. If not, ask your doctor about it -- perhaps it would work well for you!!!
I wish you the very best. Let us know how things turn out. I wish I had more advice for you, but unfortunately I don't.
God bless and please take care. Hugs, Lee
