I agree, never go against your body it knows best what you need and how much you can handle. Different people have different regeneration time, it works for gym, skin care and won't be different for pumping.
Personally I can't imagine how people are going for hours, with cupping best I can handle is 30-50 min every 2-3 days. Getting refill effects in my most stubborn parts so it still works.
