You will go through a "testing" phase where you'll have to find out what you are capable of both mentally and physically. If you overdo it, you will "pay" for it with increased symtoms later. Unfortunately it seems to be the only way to find out where you are. Just like any other exercise, you'll have to increase your capacity, stamina and endurance slowly. Just like having soreness in your muscles when you "push" it, you will have increased symptoms at times following. I've been told by by neurologist and neuropsychiatrist that this won't do me further damage.
