I really feel for you. I had it extremely bad with my second pregnancy as well, and nothing unfortunately cleared it for me. I got absolutely no sleep as I really swollen, just like you are. Just keep thinking that you're only a few weeks away from meeting bub, then it'll be gone.
I did start a thread about it, and Kelly mentioned Fast Tract. I didn't get a chance to get it as Emily arrived a few days after I posted that thread.
Here's the link to the thread
