The other ladies are right, it is the IV fluid that makes you swell, not the epidural per say. If I remember correctly, the IV fluid is necessary to regulate blood pressure so it is just a necessary irritation in order to have a more comfortable delivery so basically there's no way around it. I had the swelling as well, I remember with my first ten years ago that I tried to go home with the same shoes I went to the hospital in, they were barely even on - LOL. With my twins three years ago, I bought flip flops a couple sizes bigger than my natural size and went home with porky toes :-)
It will be hard since you already have two but you really do need to just take it easy like the doctor suggests and your body will eventually rid itself of the extra fluid. Personally, I'd be careful with the "pee pills". Your body was created to be very smart about what it needs to do when it needs to do it. It will release the fluid in the time it naturally thinks is best. I only say this because my son was very sick back in Sept. and had to be filled with tons of fluid to keep his blood pressure up and when the doctors tried to remove to much of it too fast, his blood pressure would plummit and they'd have to stop or add more back. I know, different scenario, but I'd still be careful.
