My friend just had the test done. If you can stand lots of wires attached to the body it will be no problem. If you have to potty after they get things hooked up, you have to use call button to have them help you to bathroom. Not bad thing just anoying. They ended the test at 6 a.m. in the morning, woke her up and said "are you ready to go home". She grabbed a cup of coffee from the nurses station on the way out.
