Cluster feeding = SO TIRED!

LO is one week old today and we are EBFing. Tonight she did what I can only assume is cluster feeding. She ate practically non stop for 3 hours and was ready to eat again about an hour and a half later. She's in a milk coma now, but oh wow I'm exhausted! 

Is it normal to be tired during the actual process of breastfeeding? It seems as soon as I start I feel like I could just shut my eyes and pass out, even if I wasn't all that tired beforehand.

Also, if you experienced cluster feeding, how long did it last? Is this a few days type of thing, or should I plan the next few weeks to look this way?
