The only thing I can think of that helped with my withdrawls are a HOT bath and some nyquil. I was still restless and didn't sleep well, but it helped a little with everything else. I finally fell asleep after a few hours of tossing and turning. The hot bath will help with the muscle aches, and she could take some pepto or immodium for the stomach part of it. It's a nasty nasty thing to go through, but it can be done. Be patient with her, she will most likely be irritable, and depressed as well.
