Hi,
Yes she should have calmed down by friday ok.
For future refference the easiest way to soak is to use a rub with a nice lid.
Put the 86f water (if it feels warm to you it is too hot ) in it so that it is no deeper than half way up the snakes sides and, once the snake is in it, put the lid on it and let it soak for 10-15 minutes or so.
The snake doesn't need to be underwater for the skin to loosen as the humidity in that tub will be enough to do it.
