When does the non- stop breastfeeding end?

My daughter will be 6 weeks on Wednesday. I feel like when she eats it lasts hours. For example today she's nursed 1-3 am, 6-7 am, 8-10 am 11:30-1pm, 4-5:30pm, 6- probably 9 pm. Then probably 11-12am. I know she's growing and they eat nonstop. I know my supply is good because I pump quite a bit a few times a day. But I'm ready for feedings to not take over an hour. I understand cluster feeding at night to prepare for sleep but when will our nursing sessions get shorter? I'm starting to go crazy...
