If baths are out of the question you could try foot baths, as there are many, many pores in your feet.
Baths,Sauna, lemon water, dry brushing,mild exercise can be fit in throughout your day and evening, I wouldn't say you have to have a particular schedule, just what veer works for you.
I seem to need the Epsom salt bathes early evening to help me the most.
Binders need to be taken two hours away from abx/supplements/herbals.
When I have used binders I fit them in between the times I take my herbals.
Ex: I take my herbals at 6 am, 1 pm and t 9 pm. So I have used atc or zeobind at 4 to 5 pm.
Take care and enjoy your new sauna
