wow! I'm trying to recall which compounds tend to stick to clothes, and I think it's sulphur. Add a bit of lemon juice to the rinse cycle and that should help. :)
It would be a good idea to flush the colon. Get a colonic or get your own enema bucket setup, and do a detox bath. You've got some long-buried stuff coming out now, and the faster it gets OUT the better you will feel and smell. :)
