Keep in mind, AcesAlex, that you should always take a break from wearing your binder for at least 8 hours and never, and I mean never sleep with that thing at night because you will damage your lung capacity that way. I admit that sometimes I do make the mistake of falling asleep with it on, especially after a long hard day of dialysis. Like Elis said, stay safe and good luck! Hope you enjoy your new binder and find it qualitative in its purpose.
