How difficult was it for you?

I'm 6.5 weeks pregnant and BFing my 8 month old. My nausea hasn't been as bad this time, but I've been much more lightheaded and wake up at night completely desperate for food and water and am having trouble not losing weight, even though I eat a lot. Plus my nipples are killing me so latching on is painful!

I'd like to BF LO until he is a year old, but man, this is rough!
