Has anyone used the above PRN (as needed)? After going through augmentation I have been pretty good at management of my RLS by just using tramadol when I first feel it coming on. Mostly. But sometimes it isn't enough, like last night. I took 1/2 a Levodopa/carbidopa and it knocked me out. Slept through the nigh!!! This is only the second time in a couple of weeks that I have done this. It might be something to try as a back up without risking augmentation again (at least I don't think you can augment on an occasional low dose).
